Inputs on a home built 318 for red light to red light fun
From what I understand what the op is wanting to do, I think that a 500 - 600 cfm carburetor would be good along with a good dual plane intake. 302 heads with a good comp valve job and back cut the valve's. Cam wise I'd say a 340 or similar cam. Have the block decked so pistons are at zero deck height, good quench will help with detonation. I'm thinking that if he builds as he posted that he will be disappointed. He would need at least a 3500 stall converter for the cam he would need to spin 7500 and now he would have transmission heat problems.
