I have a 440 from 1973 that cam out of a winni. I took it to my mopar motor guy and he said it had the good crank and rods. I had him bore it .30 over and installed these pistons
Speed-Pro Forged Pistons ZL2295F30
Speed-Pro Forged Pistons ZL2295F30 - SummitRacing.com
and this cam
COMP Cams Xtreme Energy Camshafts 21-220-4 - SummitRacing.com
it has stock 452 heads on it and stock 4 barrel intake.
I'm trying to guestimate the HP and Torque
by the info here what would you guess?
