I'm kinda new at posting on this Board. Learned some very valuable information about my car, thanks to all!!

I do have a cam question to ask. Performed multiple searches but to no avail. Anyway here it goes: I'm having my 350 block bored 0.030. I already have the following set up and don't plan on changing much:

89 corvette aluminum heads, ported with original springs
1.6 RR
Edelbrock headers and cat back
Ported stock intake
SLP Siamesed runners
Proted plenum
Adjustable fuel pressure regulator
9 bolt w/3.27 gears

My question, which cam will work best with this set up? I want something that has the best performace with this set up but streetable. Will the ZZ4 Cam, LT4 Hot cam, or Comp Cam XE268 work without changing my springs or 1.6 RR?

Thanks.

 

Just my opinion but I would not want to use any of those cams with stock springs, especially with 1.6 rocker arms.

If you want to get some good info maybe try searching "stock spring bind" or something close to that.

 

Comp xr264....... and matching springs.

 

Do a LPE 211/219. The ZZ4 will probably be too small and the LT4 is to big for what you have.

 

For the springs the Comp Cams CCA-981-16 will fit in the stock location and can withstand up to .530 lift.

The stockers bind at .480 and it is a small insurance policy to just get them out of there with all the work your going to do to put the cam in, your right there anyway

I am running those with my cam that is 210/220 480/480 with no problems.

It's a great combination and for the $60 the springs cost it was definately worth it.

 

Thanks for all the suggestions. I just spoke to my mechanic and he quoted me $3500 to have the block bored 0.030 over, new pistions (nothing forged), original crank turned, everything assembled and installed. I was kind of surprised, that not even including price of a new cam. So now I'm thinking why not get a ZZ4 short block and add the cam recommended (210/220 480/480), Springs (Comp Cams CCA-981-16) and bolt up my L98 Aluminum heads with 1.6RR, and intake, SLP runners and plenum.

I would imagine this would be around the same price for a better setup. Do you guys see any problems with this setup? How about the install, will the ZZ4 bolt right up to my exisitng parts without any problems? I would image that this would be very close to the ZZ4 long block.

 

If you gonna go that route order the ZZ4 Crate engine. They come complete intake to oil pan and all you need to do is remove the intake and put your TPI in its place.

Those motors come with the ZZ4 cam which you'd be crazy to take out as this motor is built to run perfectly with all the components that are installed.

All you'd need to do is a little tuning to get it to run smooth. I personally would never bolt up stock manifolds to it though. I'd go with headers and a 3" exhaust to let that motor breath.

It would be a pretty nasty setup. Check around and see what they sell for in your area. Summit sells it for $3900.

 

I have the L98 Alum. Heads and use a LPE 219/219 .560 lift w/1.6 rockers. Seems to work great. You will need better springs.
