Testy,Testy.Remember,there are few folks left that know what an OHV Ford is
Let alone setup on an performance overhaul.
First off,a 351C 4V is not big on torque,and you are adding a pretty big cam.Think loose convertor,possibly in the 3000 RPM range.Thats alot of cam for a land yacht.Expect the need for a vacuum can if stoping is high in your list.
351C's are known as a decent revver,so a 750 sounds close.I might try something a little bigger.
Power?Tuned right,expect 375-400 ponies.
