My recommendation depends on what carburetor your running and how many inches you are trying to feed a s a rat can be anywhere from 366 to twice that.

The AFB carbs be all various manufacturers (Carter, Federal Mogul, Edelbrock, etc.) will only tolerate 5-6psi before the pressure overpowers the needles and floods the carb. I have found that a stock or stock replacement fuel pump is all that is needed to feed the AFB variations in applications up 450hp.

Holleys can take 8psi and be happy.

Are you going to run a pressure regulator?

Are you concerned with a bling factor; i.e. chrome, polished aluminum?

468 cu in, Holley, I prefer not to run a regulator.

I'm going to yes the bling because I haven't cut a corner yet.

Thanks!

JMO but an Edelbrock street pump would do the job and it's aluminum if that's enough bling for you.
