We work extensively with Millennium Technologies to develop our overbore piston and block kits. Millennium Technologies is commonly recognized as the world leader in cylinder boring and plating and they happen to be the title sponsor of our race team. We also work with JE and Wiseco (team sponsor) to develop custom pistons. This is the core of our business and the culmination of years of experience.

Please note: All core cylinders, crankshafts, clutch baskets and cams must be in good condition—not broken or rusted.
