We built one maniily from left over parts when the Victors first came out. It was a 440 block with 4.15" stroke, flat top pistons and 12:1 CR, pump gas. Comp Cams 283/.683" roller cam, victor intake and a 1050 dominator. The ehads were home ported and since at the time there were no rockers available, we used Indy 440-1 rockers. They fit with minor grinding. The engine was in a 3200 lbs '69 Valiant with SS springs and run a best of 10.08/137 mph. The drivetrain also consisted of leftover parts and the engine was never really tuned, so it propably was never fully sorted out. Afterwards teh engine went in to a SC dragster, and it runs the same speeds as the common chevy revivals and has won one national championship.
