Best guess on 416 motor

I'll add that we're right at 7,000 at the stripe with a calcualted 3.7% converter slippage.

I, too would like to try 4.30's and MAYBE 4.10's at some point.

I will also say that if you already own the parts, go run it as is. One can NEVER predict what cam/gears/converters will amount to without some data (timeslips).

Your combo is close to mine. Gears should be 4.30's with a 28" tire I have 4.56’s and 4.88’s on hand; I haven't bought a carb yet,{have a 750dp} but have the rest. As for cam it is an ultradine from the guys at bullet {same place}. This is a great forum as lots of guys are running similar parts and I enjoy all comments as everyone has different building idea's:thumbup:
