Last winter we rebuilt the original numbers matching engine with a big stroker kit from Butler, ported 670 heads and a roller cam. Its now got a 4.25" stroke eagle crank... .030 over so about 460 cubes. We estimate about 475hp and over 500 ft-lbs of torque. Its got custom dished pistons so its quite happy on 93 octane and roasts the rear tires at will. Really fun to drive!
