Need a good mechanical big block pump in a hurry


The mechanical pump that happened to come with my engine tapped out at 300hp; we ran it electric and it made 402!  I want to get a good mechanical and then run it with the actual pump I'll be using and verify it on the dyno, but I'd need it by Monday.

All the pumps I can find on Amazon and Rockauto only have an inlet and an outlet, and my pump should really have a return port as well, shouldn't it? Or is the return from the filter and the pump just has an inlet and outlet?

Your pump should NOT have a return line. The filter (GF432) has the return line to the tank.

You should easily be able to source a pump at a local NAPA or AutoZone.

Amazon next-day will have it here today!

What pumps am I thinking of that had three ports, were those later emission pumps or something? I know I have the return line but I guess that comes off the filter, not the pump.
