Wow.
A lot of opinions and testimony of who did what.
where is the OP?
He Seems to be concerned about compression, and I would understand why.
if you can’t bring the CR up, put the cam in 4* advanced and don’t look to rev it to 6k.
If like me, you have to work w what you have.

I would like to see true budget performance tips for a 318, 340 / 360 cam, intake manifold and carburetor cfm, headers or exhaust manifolds, 2 1/4" or 2 1/2" exhaust. Gear ratio, which factory heads will do, etc. I have a budget to follow and I'm only wanting to add a little extra zip to the 318. Thanks everyone for your help and advice.
