The last race 471 C.I. BB I built and dyno made 720 HP at 7000 RPM and was still gaining 2 to 5 HP per 100 RPM, the customer swore he would not rev it past 7000 RPM so he had us stop their shruggy
HP is not hard to make, paying for it can be work shruggy


Me thinks if it's a 416 with a 4" stroke the bore is 4.070".

I'm guessing the cam is small for a stroker? Was the QF carb rich out of the box? The ones I've messed were pig rich as delivered.

Should be a fun driver.
