I am building basically a 454 420 magnum motor with bumped compression and a holley 800. I am switching from a gen IV motor to a gen V so i cannot use my old block mounted mechanical fuel pump. Gen V does not have provisions for the mechanical pump... so im wondering what my best option here would be for an electric fuel pump setup?
Right now i am thinking either holley black with a return style regulator or a Aeromotive 11211 marine fuel pump with return style regulator. Both these pump claim about the same specs - 140 GPH at 14 PSI. WILL THIS BE ENOUGH?
What PSI should i regulate down to?? Ive read that 7 PSI is about all the float needle in the carb can regulate.. SO should i set the fuel pump at 7 PSI at wide open throttle?? but then wouldnt it flood out all the time except when im at WOT?? Im a little confused about how you should set it?
Anyone have any thoughts?
