BACKGROUND INFO ON THIS ROTATE KIT/ HISTORY:
This is a high dollar rotating assembly. This rotating assembly was used for one dyno session. See attached dyno print at 430hp. It was in a special high performance 1967 430hp Corvette engine with 4-bolt mains #351 casting block. The engine was NEVER INSTALLED into the car. The restoration was never finished and engine never got put into the car before the person who ordered the engine build passed away. I had the complete dynoed engine. But another customer wanted only the engine block and paid $10,000 for the block. So, I took the engine apart and parted it out selling the square port heads and the #351 block. I have this balanced all forged 427 rotating assembly left. I can polish the crank and provide new rings and bearings
