K guys, I got a question. I'm thinking I need a "torque strap" (not sure what they're really called) for my engine. It's been acting up lately and I thought I had it fixed, but it started acting up again, and the first thing I checked was the timing. It looked ok, so the next thing I thought was that the cap came off because it does that a lot. It was still on. So I decided to take the cap off and check the rotor and that's when I found the problem. The cap has a huge crack in it and the rotor was totally bent. I'm thinking that my motor revved up and slammed into the firewall when I had a busted motor mount on the driver's side. I replaced both mounts but the motor still moves a lot when I rev it. Will polyurethane motor mounts help any or should I just get a torque strap? Also, does anyone actually sell them or do I have to just make my own? I'm thinking if I did get one it would help my electrical stuff, too, since it would improve the ground contact.

Any comments/opinions/advice would be great.

I've seen everything from a piece of chain, to cable, even a turnbuckle once...
You can check Jegs, or Summit, but the motor shouldn't move around all that much in teh first place. Maybe you just got some really crappy mounts??
Why not just fix the real problem as suggested in the other post. Do something with the distributer. Either "Clearance" the firewall for the stocer HEI, or look into a small body HEI. There are lots of Distributer choices available.

I am not clear if you have replaced the cap and rotor since you changed your motor mounts? If not that is the first thing I would do before changing anything else. There is little chance a bent rotor and cracked cap will stay on the motor for long.
But as far an engine movement is concerned they do move a bit when reved and that is normal, of course hitting the firewall is not normal, that should be fixed with the new mounts you installed. So I susgest you fix the problems with the distributor first and see if the car is still acting up if it is then look at the mounts / torque strap. The distributor is a much easier fix than the mounts right now and may be all that is needed. :)

Are you sure you had the cap cranked down all the way? Did you miss one of the tab screws? I did that once and the rotor cracked the cap rather violently.

Depends on what your doing with the car. Our race car has solid, and works fine, but I put urethane ones on my 67, and I hate them. For a street car use rubber. With solid you will feel evry vibration in the car, shakes and rattles galore. the benefits are that they won't break very easy, and will out last the rubber. They're also good for the reaction of the car, but they will put more twist in the car.

my dad's 406 s-10 has solid motor and trans mounts. you can expect some extra vibration,. you can also expect to go over your fasteners on a regular basis and make sure they are still torqued to spec. I know his trans pan bolts get loose, so he's got to keep them in check.

Echo the same opinion ... in general - select your parts for all mounts depending on the purpose, HP and torque of your car. If you are driving on the street most of the time and looking for a comfortable ride - then go with good quality rubber bushings and mounts (body, motor, tranny, etc.) If you will be dividing your time between strip / street - then your selection is up to what you want to tolerate during street usage. Canyon carving and road course type applications you can step up to a combination of poly mounts or your preference to stiffen up the car. For the strip or mostly strip applications - drop in aluminum body mounts, welded subframe, traction control and solid mounts for the motor, etc.

Am sure you will get much more specific input from other members who have completed projects for different purposes - but these guidelines should be pretty good to start.

Hope that helps ...

It's for a street/strip use. I never thought with solid motor mounts it works the bolts loose. I guess something that is better than the stock rubber ones.

When planning my motor install, I knew I didn't want to go solid because it didn't make much sense for a car that won't see the track more than a few times a year. For a dedicated racer, possibly.

I also didn't want to worry about rubber ones wearing out quickly and needing to be replaced.

Since I'm not overly concerned with vibration that is going to be tranmitted using poly engine mounts, I chose those. We'll see how the car likes it. My thought is that unless you're driving the car every day, poly is the way to go, which is why I went that way.

SuperNova69
17th-March-2005, 08:18 PM
Yeah, when I saw the crack in the cap I immediately went and bought a new cap and rotor. I don't know how good the mounts are, I got them from Autozone (didn't even know they sold them there!) and they looked a LOT better than my old ones. If I rev my engine up from under the hood, you can see the rubber stretching, though. I'm thinking poly mounts might be a future upgrade...or maybe solid...I've probably opened up a can of worms just mentioning those, :D .

And yes, I plan on eventually getting one of those Crane Cams distributors with the allen wrench adjustable timing, but since it costs $320 for the distributor, another $150 or so for the box (since it says it needs one), and then another $50 or so for a coil, it'll be a while before I can get it. So this big old distributor will have to last.

The pre 73 mounts are more prone to strectching and breaking. That's why GM went to the clamshell mounts. Either put a torque limiter on the drivers side or try this old trick:

Install a solid mount on the drivers side and a regular rubber one on the pass side. Use a self locking nut on the horizontal bolt on the solid side. Don't snug it too tight. That way the engine can float on the rubber mount but not lift.

SuperNova69
17th-March-2005, 10:38 PM
Thanks, Paul. I'll probably do whatever's cheaper. I don't mind having to use a solid mount on the driver's side since I want this to be a corner carver, so it's gonna have to have a pretty rigid chassis.

I'll start looking into some solid mounts.

I'd wrap a chain around and call it a day. Nothing more than a dollar or two. Didn't they have them as a factory option on the Z/28's?

The only thing I could find were ground straps, and I don't know if that would be tough enough to hold the engine down or if it's just a cheap, light metal strap. It was $19.95 at Classic Industries, and solid mounts were $21.88 from Summit, so I just got the mounts. I'd rather have the mount anyway, as I think the strap would be an eye sore.

We'll see how I like the new mounts.

why not put solid motor mounts in .my 58 is running @ 500 lbs of torque and rubber or poly will not hold up long.those straps look cheap.i put my threw the test every weekend and never have any problem. :chev:

the mechanic
18th-March-2005, 12:24 PM
what i always did here was mentioned before get a peice of chain and a peice of black rubber hose to cover the chain and cut it so its long enough to let the mount work properly but not long enough that it can snap the mount. the hose will make it look better and keep it from rattaling(sp?)
i agree with whoever said solid mounts are terrible in a daily driver or a weekend cruiser at least IMO.

Paul Wright
18th-March-2005, 12:39 PM
A compromise which reduces the vibration problem is using only one solid mount as described in my post above. Plus if you split the set with a buddy it's pretty cheap too.

Mike Goble
18th-March-2005, 10:35 PM
I use stock rubber mounts and an adjustable torque strap.

urban rat
18th-March-2005, 11:41 PM
I run solid everything but will switch the trans to poly to remove a little bit of the drivetrain vibration. I personally love the feeling and drive mostly on the street but I also did not want to twist it all up with the torque so she is as stiff as I could make her. Heck it kinda makes me giggle at the traffic lights.

SuperNova69
21st-March-2005, 11:21 PM
Well, I did what Paul advised and it's perfect. The engine doesn't move at all now, the whole car does. :D And you can't even really tell there's a difference except for when the idle is really low. Other than that, it's like it still has the rubber mounts.

My only complaint is that even though it says it's for a Chevy, it didn't fit right out of the box. The space that mounted to the frame was too narrow, so I had to bend it a bit, and then the holes for the engine wouldn't line up, so I had to really "customize" it. I thought that was a bunch of crap. It took me a couple minutes to get the old one out, but it took about 3 hours to finally get the stupid solid one to fit. :mad:

Other than that, I love it. We'll see if anything rattles loose/breaks, etc, but I doubt it.

Thanks for the tip, Paul.

I have the same problem. Motor twists too much, breaks motor mounts, bends distributors, etc... My car has a short chain that goes from the frame to a header bolt just behind the power steering pump. From what I understand the factory even installed some of these after the fact (not sure about a chain but something [strap - whatever] - this isn't a new problem on the big blocks. Correct me if I'm wrong.

if your using solid motor mounts you should run a solid tranny mount too!

You can get a similar part at most any hardware store in the turnbuckle department. It won't look as nice as Waynes, but it will function the same.

I like the new Summit setup. It makes finding parts a lot easier for me by allowing me to zoom in on exactly what I want.

Yep there was one of them high tech hardware store turn buckles in my car when I bought it :D . Previous owner ran nitrous so I suspect that is why it is there. Seems to work well and I didnt really see any reason to remove it. Of course like, Mike said, the one from Summit is much nicer to look at.

A chain was a common fix installed at the factory in the 60's, but not for engine rock, but to prevent problems in accidents. The old cars had a solid accelerator shaft. In even a mild frontal inpact, the motor mounts would break and the engine would move forward and get partial or WOT. Having the car take off by itself was not a good idea. So the fix. Chain on the driver side exhaust to frame. Then if the mounts broke, it would force the engine to twist to the left, forcing the throttle closed.

Man what a cheap and simple fix that is for a potentally fatal design issue. I would never have thought the chain was there for that reason but it makes a lot of sense. ;)

Hi phantom12321,

Having to move/change the mounts on the frame only applies to engine swaps in 1972 & earlier Novas.

In 1973, GM changed over to the "clamshell" type engine mounts. The lower halves of these mounts are the same for both inline-6 and small block V8 engines. They stay in the same set of holes as well.

Unless the inner rubber cores are bad and need to be replaced, there's no need to even unbolt the mounts from the subframe.

Your engine swap will however require you to change the upper mount brackets (the ones that attach to the engine block with 3 bolts). I think you can still buy these brackets from GM but they're a bit pricey. They should be a common find at a junkyard though. And if your 350 came from a 73 or newer vehicle, it may already have the correct mount brackets bolted to the block. Keep in mind that there were at least a couple different heights of these brackets used in different vehicles. The ones you want measure 2-1/4" from the center of the large through-bolt hole to the side that faces the engine block.

O.K., after reading around on this site, I realize you guys are problably the best to ask. When I was planning to put a BBC on my nova, (1970) I bought new BBC factory frame mounts. When I got them, one of them was higher than the other. After double checking, I was told that these where the right part numbers, and installed the engine. Like I figured, the engine leaned a little to one side. No one else has been able to notice unless I point it out. Is it just me, or has anyone else ran into this issue? :confused:

The engine leans towards the passenger side to help clear the power booster....also helps when installing headers as this helps clear the power steering box.
The passenger side mount is noticeably shorter than the small block one.
This is also the reason for a big block crossmember.
The engine also sits closer towards radiator support.....hence the big block shroud.
I guess the offset is not that much so now one really notices.....believe me I've been through all this the past month :D

Also read Best of Tech engine mount questions (http://stevesnovasite.com/forums/showthread.php?t=16190)

Even the the big block is closer to the radiator because the engine is longer, the rear of the block is in the same place as the small block. GM standardized the Rear Face of Block so engines can interchange easily.

You are using 2 different style mounts. Your '72 has the early style mounts where the rubber is attached to the block. Starting in 1973 GM switched over to the clamshell style mounts where the rubber is attached to the frame.

The difference is the mounting plate/frame brackets on the subframe.:)My 72 originally came with a 307. When I was recently replacing the 350 that was in the car when I bought it I purchased a set of motor mounts specifying a 350. They didn't fit. I spent hours trying to figure out what the motor was hanging up on, loosening headers, etc. Then lifted the motor up high enough to take the new motor mounts off and try to slide them over thee frame mounts. Too small by maybe 1/8". Ended up putting the old motor mounts back on the motor and it was bolted in within 10 minutes.

When it comes to motor mounts, SBC is not SBC. They do differ.

Check out https://www.rockauto.com/applet3.html

And compare the PN's between different SB's from year to year.

Moral of the story is that if the frame mounts are original to the car, you need to use motor mounts according to the original motor.

Orange hit it. I didn't realize the later model Nova's had different frame mounts for different size V8s (307/350etc). 2nd gens have "V8 frame mounts" with no distinction between the 283 and 327. I need to quite answering 3rd gen questions and leave them up to the experts like orange who own one.

I have a question regarding motor mounts for a 73 SB car. I am in need of engine frame brackets and everywhere I checked they are disc. You can still buy the half of the mount that bolts to the subframe but not the half that bolts to the motor. Does anyone know where to get them or do mounts from something else fit? Its a driver so solid mounts are out. Any help would be greatly appreciated.

Hi paulanntim,

I don't think anyone reproduces these brackets yet, and if the GM ones are now discontinued, that leaves salvage yards as about the only option.

These "clamshell" type engine mounts were used in lots of 1973 & up GM vehicles. However, there were at least 2 (if not more) different heights of V8 engine mount brackets. 73-79 Novas and 73-81 Camaros with small block Chevy V8's will probably be the best places to look. The correct brackets for Novas measure 2 1/4" from the center of the large through-bolt hole to the side that faces the engine block.

Sorry...

Well I purchased my BB motor frame mounts...correct ones ('68 Nova/'67-'68 Camaro only) and the supposed correct motor mounts for a BB on a '68 Nova.

Tha frame mounts are 2 1/2" wide and the motor mounts are 2 1/4" wide, therefore the motor mounts do not slide over the frame mounts.

Is this a normal problem or what do I need to do? The motor mounts I purchased are Lakewood Muscle Mount (recommended) and there is only one number for the bbc mount ((I posted a question here as to what you all used and did not get any answer)).

Any suggestions?????

Brian,

I am attempting to do the same thing. It appears the 68 frame mounts are different than the 69+ mounts. I have frame mounts for a 69 and they measure 2 1/4 inch wide.

Since I have only the frame mounts installed so far, I will be interested in how this works out for you.

well I'm pretty sure that I once read that the '68 BB cars used SB frame mounts...(about 70% sure I read that)...anyway I went out to the garage and measured my '69 SB frame mounts and they are indeed 2 1/4" wide which would fit your motor mount. Like I said I think I read this and it is one of the many things that make the '68 special...hopefully this is both right and helpful.:)

So what do you all suggest I use? Is there a "right" motor mount to get? Or do I need different Frame Mounts?

just a thought but could you not use the '67-'68 Camaro motor mount??? you would think it should match the '68 Nova/'67-'68 Camaro frame mount you are using?....this is just speculation on my part as i dont know what motor mount you are currently using other than it having roughly the same width as a SB mount...just a thought:)

I could never figure out why the 68 mounts are different. Did your car have a small block or a 6cyl previously? My 68 was originally a 6cyl, but had a SB when I got it, so I am unsure what mounts it used to have...

SyncroMush..Yes, it was a 6cyl. I thought the same thing and do not know if I should get the factory versions since they are not interlocked.
Lakewood stated that I could modify the Frame mounts by cutting them narrower and welding plates back on the sides to beef them up. What do you all thing of doing this? I have a welder and also my buiness has a weld shop (tig, mig, etc.), so welding it back together would not be a problem.

The first gen Chevy 2's have different frame perches and motor mounts for 6's and 8's. You will need both to swap in a V-8. The February 2006 Nova Times has a great article on the V-8 swap. NNN has any of the parts you might need.

NNN, Chevy2Only, Classic Industries... i think just about all the restoration suppliers can supply ya with a V8 conversion kit... the mounts are still available from yer local parts house and are quite inexpensive... you'll have ta double check my memory, but i believe the numbers are 2142 for the std non-interlocking mount, the 2167 or 2267 is for the interlocking style... (check the 2167/2267 for application ;) )

check yer local parts house and ask ta see the buyer's guide, it'll have pictures and applications listed ;)

you can get by with the non interlocking on the right, interlocking on the left... if ya like. i prefer the interlocking on both sides...



hope i helped :D

You can't run a solid or poly mount on thransmission without using the same on the engine. If you have rubber mounts on the engine the engine will twist a bit and break the tailhousing on the transmission.

Real McCoy

So if Energy Suspension 3.1117 will work, the right gm pn will be 3962748?
And the moroso solids will be 62510. They are listed to fit Chevy II, Nova 1970-72 350 and Chevy II, Nova 1968-69 350. It dosent looks right to me.

Or maybe thats right becuse i emailed classic industries an asked which motor mounts to use with ci pn K701, the same as gm pn 3950113, 3950114. and the answer i got was: Use K701 with 3962748 motor mount.

This frame/motor mount issue seems to be a real mess, and no direct answers


So i will try the 3962748 or the moroso 62510 and see how it fits. Then i will post my results.

17th-May-2006, 10:38 PM
You'll need to measure the width of the frame mounts where the motor mounts goes over it. I've been going through some issues of finding the right frame mounts because GM made 3 different widths: 2 3/8", 2 1/2", and 2 5/8". I believe the big block mounts are 2 3/8" but don't hold me to it. Once you know this measurement call whoever you're buying the mounts from and they should be able to tell you which one to use.

Driver's side? If it's the driver's side then replace it with a steel or polyurethane one and keep the passenger side with a rubber mount. You will have better strenght on the one side and some vibration dampening on the other side.

Pick
1st-August-2006, 10:41 PM
Can't remember if your's is a '73 or '74. '74 (at least some of them) went to the style mount where the rubber was on the part that bolts to the frame and then an all metal bracket mounted to the engine. If your's is like that, (and the following are JEGS part numbers) I used Moroso 710-62630 mounts for the part that bolts to the frame, and Moroso 710-62510 for the part that bolts to the motor. I kept getting conflicting information on whether to run a solid or poly mount for the trans, but finally settled on an Energy Suspension 355-3-1108G poly mount for the trans. Very happy with it so far. Not really much vibration at all.

A trick to installing them is to leave the frame mount part loose until you have the though bolts in, then tighten them down.

***EDIT*** I just rechecked my receipt - It was a Moroso 710-62515 NOT a 710-625510 as posted above.

Moroso makes solids mounts for most chevy applications, ya gotta measure your stock mounts an compare their dimensions on their solids. Its easy to pic the right one.

Someone converted my '69 to a big block many years ago. Currently, the motormounts are solid, i.e. no rubber, just steel. Can anyone tell me what the correct setup is? Thanks.

I'll have a set going on ebay later on this evening. They are Mr. Gasket solid mounts. For a 69 Nova with a BB, part# 3672 is recommended. I have them for $15 if you're interested. Dave

The rubber block mounts should be readily available at the parts store.
Your frame brackets may be correct or they could be small block stands or who knows?
You may have to take it apart and check for PN stampings or measure the hole height from the mounting surface.
Here's my frame mount page (http://www.geocities.com/pcwright77/files/framemnt.html). I need to update it with pictures and other dimensions once I get this big block mount thing figured out.


You should read the offset Big Block trans mount thread (http://www.stevesnovasite.com/forums/showthread.php?t=44405) for more on the subject.

Does anybody know who sells the clamshells for a 350 motor in a '73 nova? I've looked everywhere with no luck. I dropped the motor in with solid motor mounts from Summit and it's sitting too high. If I can find new clamshells I'll just go back to them instead of messing with the solid mounts.

Summit should have them in polyurethane...Ask for motor mounts for a '74 Nova. Or if you want the factory rubber style, go to your local parts place and get them for a '74 Nova.

I tore up my stock type rubber mounts, and want to go with a solid mount. I only need the part that bolts to the frame right? I can use the stock mount that bolts to the block... right?

This is a replacment for the part that bolts to the block right?

Be sure to change your transmission mount to a solid one too when you change out to solid motor mounts. Always match the two so that nothing in betweeen (bellhousing, etc) gets twisted with the torque and breaks/cracks.

Go solid on one side and rubber on the other. Did the driver's side fail?

The frame mounts stay the same--you change the engine side of the mounts. I run all solid mounts; some people insist you can't do that without breakage--some say the opposite--some don't have a clue! I've been running ALL solids for many years, never broke anything yet. I had a urethane trans mount for a short time, but it ripped in half.
If your car is a daily driver, you'll hate the solids.

No. solid tranny mounts usually tansfer a ton of noise. There is also no stress or very little torque applied to the tranny mount. Tranny mount is to hold UP the tranny thats it. Ive had solid engine mounts and a stock tranny mount on my car through several combos. If your tranny mount is ripping, its most likely caused by something else not working right.... Pinion coming up to much or something. I have over 600rwhp going through a stock tranny mount. Granted its a 4 link car and nothing bends and twists.

on a uni body type car like a Nova solid motor mounts will shake the whole car. It will look cool when you rev the motor bacause the whole car will rock back and forth even more. I have solid mounts on my chevelle with a stock trans mount and sitting in the car you couldn't tell it had solid mount because the car doesnt shake around. then again a Chevelle is a full chassis car with body mount between frame and body. i guess solid mount would be ok on 3rd gen and up but pretty harsh on a 1st or 2nd gen. thats my 202 cents:D

Your mount is completely different from mine--350's had one style; 307's had another--I think my frame mounts were originally from a 307 style ( I don't remember, they came from a junkyard) Mine are just like a metal stand with the bolt hole thru the middle, and the solid mount just straddles the stand. On my stock mounts the rubber was on the engine side.

He Swapped To Soild And Called Ne The Next Day And Told Me The Car Felt Alot Better To Drive And While At A Light.

i have ran solid motor mounts on everything i've had, daily drivers to race cars, 72 elcamino 454bbc th400, 69 camaro 396bbc 4 speed, 66 nova 350sbc th350, 72 nova 400sbc th400, 68 nova 427bbc th400, just to name a few, you should run a rubber or urethane trans mount. dont run a solid trans mount with solid motor mounts because something has to give, and it's gonna be the trans case. the vibration is very minor not a concern at all and if you have a decent cam its gonna vibrate anyways.

I used to run solid motor mounts with a rubber trans mount and hated it on the street. It was so bad the emblems vibrated off my car. I got home one night and one of the SS emblems was missing and the other side was about to fall off. In addition the dash rattled and there were annoying harmonics in the doors and sheet metal. It sucked. I finally ditched them and went with Energy Suspensions Urethane motor and tranny mounts. Solved all my issues and they never broke. Stiffer than stock but not rock-hard like solid mounts. They are also "captured' so even if the rubber would break the engine isn't going anywhere.

I went from stock to solid on my car (mostly a drag car now), and I can tell you that if I were to put it back on the street, I would NOT run solid. My engine is completely balanced, but it vibrates like there's no tomorrow (typical race car).

FWIW, I run a stock tranny mount with the solid motor and have never had a problem.

Energy Suspension makes polyurethane engine mount inserts that fit 73-79 Novas. They're part number 3.1116 and replace only the rubber portion. You re-use the stock metal shells and brackets.

In lue of the solid motor mounts for the street, try strapping the engine on the pasenger side. SBCs originally used front motor mounts. You can put a solid bar mount from the front mount to the frame. It will requre a mounting point on the frame, but it will allow you to keep your rubber or urethane mounts and stop the motor from twisting. It has the added benefit of stopping the parasidic power loss from the engine twisting

Go with the energy suspension poly mounts. You won't break one of them unless you're making real big power with big traction. They are a little stiffer than stock but a lot better than solid. I ran the Energy Suspension trans mount too with my 406.

Bscman
4th-April-2007, 12:21 AM
I've seen people fab up rods to limit engine torque.

A bracket is welded to the frame, and essentially a pipe threaded at each end with rod ends is used. One rod end butts right up on the block and a bolt goes through it, the other end goes in the bracket on the frame and a bolt run through it.

IIRC, comp engineering makes a similar device.

GM even had a part in the 60's that was a cable type restraint that goes from the frame to the cylinder head. They're on ebay quite often.

I have heard that the stock rubber ones will tear and separate with a modified and or high hoes/torque motor. My 383 is not a monster of any sort but it should make 400-450 hp and about the same torque. Not sure if the stock rubber glued to metal mounts will last.

Energy Suspension (summit part #) ENS-3-1114G fits the early Nova V8 frame towers for motor mounts. I used these from the kit ENS-3-1120G, which included the trans mount also.

The short/wide mounts on the ones you want. I used these on my car and had no problems fitting them to my 95 block and frame towers.

This is what I was trying to describe earlier...if you're crafty, and can get rod ends available locally, they're quite easy to make--and probably half the price.
If you're really lazy, some female rod ends and some thread stock would would just as well. Use heat-shrink or rubber hose to hide the threads. Probably have it built for under $20
Just a thought.....

They aren't - except they never came from the factory with a V-8. So if you are running a V-8, you are most-likely using 64-67 frame mounts.


I like solid mounts. I run em with no issues at all.

When I ran solid mounts my emblems vibrated off my car and the dash vibrated and I had rattling in my doors and other harmonics. It was pretty rough. OK for a race car but annoying on the street.

There are other manufacturers that make high-performance motor mounts other than Energy Suspensions. Lakewood makes a high durometer rubber mount that is supposed to be pretty strong and they list a part number for 64-67 Chevy II. There are also a couple others that make polyurethane mounts that will fit Novas.

So i got solid motor mounts but some one told me that i HAVE to run a solid tranny mount? Is this true?

NO.... Dont do it!!! you'll break the bellhousing!!! use a good polly mount on the trans.......... I have seen to many broken trans bell housings due to chassis flex in stock chassis with all three mounts solid...

stock sub frames flex too much.... for 3 point solid mounting

No, do not use a solid trans mount with the solid engine mounts. Some people get away with it but the general consensus is NO.

Nonsense! I've run solid mounts at all points for over 10 years.

I have a bar, not a full cage.

That's cause all the rust in your car allows for some flex :D

Mike, I'm actually going to disagree with you on this one. As stated by others, solid in the front, urethane on the trans.

I'm sure solid would work but I don't want to experiment with my case.

I dont want to hijack this thread but i have a related question. is there much benefit as far as vibration is concerned to just run one solid and one urethane mount on the engine? I have a set of solid mounts but just wondering if i should buy one urethane. rob.

Not to sound like an azz but how much can you really pick up with solid mounts? A regular mount can flex maybe what, 1/4 to 1/2 inch? Is that going to be the difference between a 2.00 60ft time and 1.50 60ft. time? I doubt it, IMHO solid mounts should be left to full cage cars that only spend time at the drag strip. I like my molars where they are, I don't want to be driving around and have things start falling off the car because of the vibration.

Actually it's just rust colored--we don't do rust here in California!

Jeff, everyone is entitled to their opinion--right or wrong. hehehe.
I've seen more cars break trans cases from all the flexing due to rubber mounts. I tried a urethane mount; it lasted a few months before it tore itself apart.
It just doesn't make sense to me to have one part bolted solid, yet the other end is flopping around in rubber--tie it all together as one solid unit and the car should work better.

You have a point; I've left a trail of parts behind! One day I started looking around under the hood (I try to avoid that) and discovered almost all the motor mount bolts were gone!!

What probably happens (stating the obvious) is the front of the frame twists a lot to the right more so than the middle of the frame. If the tranny mount is solid, something has to give. I imagine people also break tail housings. Frankly I could see that more than breaking the entire bell housing.

I have solid engine mounts and a rubber trans mount. No problems and the ride is not all that bad. No broken tailshafts.

I imagine the shape your body mounts are in might play a part in all this also. A body bolted more solidly to the frame could add SOME rigidity. Guess it depends on the car and the shape everything else is in.

Go with poly engine and trans mounts. Best of both worlds. Solid mounts suck if you plan to drive the car on the street.

I used to have solid monts. My dash rattled, my doors and windows rattled, all of the emblems vibrated off the fenders, and all kind of annoying harmonics.

I'm not kidding! After a month or so I walked around the car and one of the fender "V"s had fallen-off. Some of the others were either coming loose or were almost ready to fall-off too!

For me solid mounts are great for a drag car but suck on a street/strip or street machine.

X2 on that!! I have been doing street cars for a long time and have a real dislike for solid mounts, especially since the new mounts are so good!

I did this on my old 63 because I kept snapping the ball on the enigne side when I ran a manual trans. Kepp that from happening.

Wow now this thread is entertaining! My 62 Chevy II has had solid mounts in the front and stock rubber in the back for close to 35 years. My front mounts are even bolted to the front cross member. Yea I know yer gonna say that thats not gonna hold up and is wrong, but this car grew up on bad country roads and survived just fine. Nothing ever fell off or vibrated loose, unless you include my brain!
