502's with Prochargers completely rebuilt after piston meltdown, ported and polished heads

640 HP @ 5700 RPM w/6 lbs. boost
665 TQ @ 4500 RPM (not sure about RPM)

These were give to me over the phone. Hopefully I will finally be able to pick up boat tomarrow with spec sheet. It has been a long and stressfull wait.

Look like pretty good numbers

Good luck with everyting

I never really understood the max rpm our engines run at.
Is it max horse or max torque?
Or someplace in between?
Where would/will you run yours at?

5700? Rpm isn't that a little high for a 502? Or is this not a stock configuration? Is this a stage 1 or 3 setup?

The Prochargers are stage 1. The "dyno" and "in the boat" are two diff. things. Before the rebuild the boost was 5.5 @ 5000 RPM. I will not spin over 5200! The heavier the load on these superchargers the more boost. Once it is in my hands I will post the actual results,......speed that is!

Man all you guys are making me jelous. Tomarrow afternoon I am hitting mine again!!!

What outdrives you running????

Bravos , for now
