sb 307 help
I have an early 70's 307 completely rebuilt except carb and intake. My question is what carb/intake combo will give me top performance. It has a stock intake with a 2bbl carb. The motor also has a beefy cam. The motor has never been started since the rebuild.

Intake/Carb
Use an aftermarket dual plane manifold, with around 600 cfm vac secondary carb. Hard to go wrong there!
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
