Carb'ed Stroker with 470 Truck Avenger what PSI for fuel

[cuban11182]

I have a Newcomer Racing Stroker being built and want to see what fuel PSI I will need to make the Holley happy. I've read between 4-7 psi, but thought I'd ask before I start planning on what to do.

Thanks in advance

Whatever pressure the carb manufacture recommends.
Ultimate fuel/air metering will be determined by the carb jets, springs and adjustments.

Holleys prefer 7 psi. Carter and edelbrock about 5

Honestly you will probably have better throttle response with the 390
