Forged internals, 9:1 comp, 142 supercharger, boost carb, 355 cubes, AFR Heads, mild cam... it came out of my 69 Camaro. More than enough power for the little car, still got a 200-4r behind it, fully built. The car should be close to the same weight it was before we started the swap, which was 1456 lbs.
