Well sirs, I intend on a pretty serious street car. I'd love track time also.
So, I'm thinking forged pistons, proper cam, I have a 292 exhaust manifold, offy intake.
There will be a j & s unit.
Meth injection, also.

Question: if I build a box for the carb, what kind of boost can the carb take? I know the fuel pressure needs to be 4-7 psi above maximum boost. The floats need to be filled. Choke horn removed. Anything else?

I have no concerns with doing a draw through at 20 psi boost. It's just not optimal.
