Hello All

Just joined the site yesterday.

Seems to be a great site from what little I have seen so far.

I have a 67 Nova 2 door that I am transplanting an 05 Chevy Trailblazer 4.2L Engine and 4L60E Transmission into.

Has anyone here done anything like this, or know of anyone else who is doing the same type of swap?

It is almost a drop in fit so far, the only major problems seem to be the steering, I think that can be overcome by using a rack and pinion from another vehicle without too much of a head ache.

Anyone have any good idea's on what type of gas tank to use or that will fit in order to get a few more gallons of gas for long trips and that will allow the electric in-tank fuel pump to be retro-fitted into it for the engine SFI?

Again, a GREAT SITE

As far as the tank, do a search for 55,56,57, chevy fuel tanks. Some of the old tri -5's had fuel injection, and there are a couple of companies making these tanks, they are a bit pricey at 5-600 bucks, and are upgraded to todays equipment, but not as costly as the stainless one at 900+....:eek:

If you are good at fabrication, there are several threads at ls1 tech that show you how to chop up a tank and add the sump and in tank pump. Mileage shouldn't be an issue with the 4.3, unless you "tweak" it up a lot.

You could also do a Church Boys rack and pinion to solve the steering issue, cheaper than a clip , and a trick setup all the way around.

Good luck on your project and post pictures often.....

Hello

TomM, the engine is the 4.2L Inline "6" Cylinder engine, not the "V" 4.3L engine, Just FYI, seems like a lot of people get these two mixed up for some reason, my gress it is, because they are BOTH SIX's

Just a little about the 4.2L 6 cylinder engine, for anyone that doesn't Know much about them/it.

"All Aluminum Engine" Top to Bottom execpt for the composit cams/valve cover, DOHC, 4 valves per cylinder, stock fuel limiting at 6300 RPM's

It has Variable Valve Timing on the Exhaust Cam, but not the Intake Cam.

Bare engine weight Approx. 360 Pounds with Exhaust manifold, minus plastic intake and all accessories and bolt on items, ie mounts etc.

Pretty light for a complete engine. Less Weight means quicker acceleration, RIGHT!

6 into 1 exhaust cast iron manifold/header with a "3" exhaust outlet to the STOCK, MANDRAL BENT 3" EXHAUST TUBING, and exhaust system, It has a 2.5 inch outlet at the rear under the bumper. Pretty free flowing for a 4.2L (256 Cu. In.) Engine

All cylinders have Replacable Sleeves, pistons are Pre-fit at factory with a bore of 93mm/3.66 IN., stroke of 102mm/4.01 in. Any over boring is not recomended as it severly weakens the main line of the block, and the siameezed cylinders.

(Hyper-Utetcic? MAHLE PISTONS and MOLLY RINGS, Factory OEM Parts)

No honing or boring required EVER, JUST R&R Sleeve and Piston as a matched set. The Sleeve does not even need honing since the crosshatching is done at the time of manufactur, and is not recommended at ALL by the Factory.

Engine rated at 285 HP at 5500 RPM's, 291 H.P. for 06, I think the RPM is right, but not completly sure about it right now.

GM Debued The Trailblazer in 2000, and raced in the Baha 1000, against a field of other V8 powered Racers.

The Trailblazer recieved the Best Performance Award for it's efforts.

The same Trailblazer also "WON THE RACE!!!!!" Not too shabby for a little 6 on it's first OFFICIAL race. I feel that it has the Potintial to be the new reincarnation of the ol'e GMC 302 "Jimmy" that terrorised the Drag Strips and the Lakes in earlier times.

They (GM), took it to Pikes Peak and Womped on them Again.

In Race form, from GM it was rated at 675 HP @ 7500 RPM's

So as you can tell the engine has LOTS AND LOTS OF POTENTIAL,

How fast can you afford to GO!

Any way my retro-fit is completly stock as it was made in 05, (At least for the forseable furure, got to get running first, RIGHT)

I was lucky enough to be able to pull the engine and trans myself, I pulled it out ROOTS and ALL, I also got everything that was left behind, I.E., complete Fuel system, elecrtical system, with All the Electrical Harness's, 3" Exhaust system, Etc; Etc.

I think everyone will be seeing A LOT OF THESE ENGINES in the near future that will be retro-fit into other vehicles.

I have heard of a 66 Nova Wagon on the drag strip that turns in the 8's with 1400 HP, at 10,000 RPM's I havent seen it yet, maybe some can find or already has the link, It would be great to see for sure.

I guess I have rambled long enough for now.

Take Care

Dusty
