Hello all fellow TCers. Can any one tell me, to what horse power and or RPM my 1972 402BB 3 line A/C delco fuel pump feeding my Rochester is good too?????
Gary.

In the neighborhood of 425-450, assuming an unrestricted uncrustified fuel system between the sump and the pump.

RPM will depend on what fuel pump rod you're running. A stock one will limit it to not much over 6000 RPM for any length of time.

RB69 thanks for your thoughts, any one else care to add anything.Running 440 horse on dyno should I replace pump. I just purchased a new OE unit will it be adequate????

Any other thoughts????? or opinions!!
