I have a 71 nova with a 350 in it. My question is what is the maximum lift with the stock springs that i can have. I was thinking about geting the summit 1106 cam. will this work. If not what is the biggest i can have. The specs on this cam are 234/234 duration @.050, and .488/.488 lift. Thanks

If the stock springs are on stock heads, don't even waste your time. I was running a .449 (.480 with 1.6 rockers) [email protected] on stock springs and they gave out at about 4500 rpm. Plus , the iron heads peak at about 450 lift. If your going with a cam that big, get some good heads(most come with decent valve springs) I put afr 195 on my engine and ran low 13's with that small cam. That cam your looking at, with good heads, will get you in the 12's easily

My old cam is close to the one loneagle recomended. If you want it I'll sent it out to ya, I hate to see it sit on my bench. You have to get new lifters, I yanked out the old ones and didn't keep them numbered. Just don't put a big stall on there, you'll rev right through the meat of the power band.

I'm running the Summit 1108 cam, with the 'Z28' springs, in low-buck, stock iron heads. I have opted for alum roller rockers.

i'm not sure of the cost but crane has some stock dia springs made from H-2 (I think) tool steel...anyway they are good for lifts up to .600"...I have ran them myself and had no problems hitting 6500+rpm without missing a beat:)

I took my car for a dynotune and the guy jeted down the secondarys three #'s, but my #7 ign wire was arking on the header giving him a rich reading(failed emmissions cause of that). After all was said and done after new wires, I think I went up one # bigger than stock on the secondarys for my last race of the year on a cool fall night. And I still lost. Moving up to a xe274 solid cam and a 750 dbl pump, so all the fun starts over again.

First of all do not use the stock springs. Get the right springs for that cam. Second of all why do you need the biggest cam? Oh, never mind. I give up.

Uh...no.
I think when he asked for a sound clip was the clue that gave it away. He wants it big enough to sound like a funny car idling and he's assuming he won't have any problems with it if it's not too big. All you got to do is pick the right $79.95 cam in the Summit catalog.

This question is a old as they come....asked about 10,000 times. I'm sorry if I get tired of it.

Couldn't you run a stock cam and just remove one of the plug wires for a nice, rough idle?

I may be a little more grouchy than usual because of the whiplash shift time change, but your lame excuse irritates me for some reason. Maybe it's because it doesn't ring true. Your questions didn't mention CR or head flow or a number of parameters that would be relevant. You just asked how big a cam you could fit without bothering to check and measure anything. Asking how it "sounds" isn't a criteria. An engine will sound good (Or "bad" in your case) if it's built right.

I understand why people want to have their engine sound "bad" imitating a race car idle, but they often don't understand that the race car sound is a by product of poor efficiency at low rpm. They also don't understand that "big" cams don't perform well in low compression engines, especially with stock heads that don't flow past .450" lift (or less), that pushrods and springs and other factors may need upgrading.

Overcammed engines don't sound good. An expert can hear that. So basically people with overcammed, low compression, low flow stock heads and valve floating springs aren't fooling anybody who knows anything.

IMO, the cam you've selected isn't the best choice, but what do I know? good luck.

1BAD71- The Crane 274 camshaft I mentioned earlier will work fine for you, but sometimes you just have to "live and learn"
