We began our powerful adventure with a new Gen VI H.O. 502 from GM Performance Parts. It comes with iron, rectangle-port heads, an aluminum dual-plane intake, a damper, a water pump, and a flexplate. Inside the short-block is a steel crank and forged pistons along with a hydraulic roller cam (211/230 degrees at 0.050 and 0.510/0.540-inch lift).
