C4 head and cam
Does anyone know what the port and chamber size is on my stock heads ? What would be a good cam and head set-up for this 350 with automatic. I would like a little better performance .

What year is your car. I think most L98's have a 58cc chamber....hopefully someone will chime in and set me straight. While mine is apart I'll have to remember to measure how far down the piston sits from the block at TDC.

Re: C4 head and cam (drive it)
So can you set up the top end of a 86 vette with 87and later parts. If so do I need to change pushrod length if I go with roller cam and roller rocker? Does anyone know what port and chamber size I should go with on a stock 350. Also what about valve spring size? Oh yeah Kelseyville is about 100 miles north of S.F. way up in the sticks.

Early L98 iron heads were 76cc. 1986 aluminum heads were a bit smaller. Not sure on the size. In 1987, even smaller, again I'm not sure on the size, (I wanna say 68cc). :smash:
