Default fuel system design

Running a 351w with around 500hp. Trying to figure out a good place to start. Thinking 8an fuel line with 50gph fuel pump and 700cfm carb. Does this sound close? Should I run a pressure gauge or regulator?

Thanks

I assume gas here, a holley black pump is what I would look at. -8 from back to regulator in front by carb -8 out of regulator to carb. Yes on gauge you will need to set the pressure with the regulator.

Actually jegs sells a 'generic' electric pump kit which is probably just a Holley blue or black in diguise anyway.

I bought one for the boys mustang (351W), regulator even had the holley insignia on it.

Run # 8 line to the engine bay and set the regulator @ 6.5 to 7 psi and your good to go.

I'd go with a 750 cfm carb though.
