| Heretic 427ci Short-Block Build In this video, we built and assembled the heart of the Heretic Mustang's 427ci LSX engine. Starting with a GM LSX block, we added a Lunati 4.00-inch crankshaft, Lunati rods, JE Pistons, and complete ARP hardware. A Comp Cams hydraulic roller would be tapped to make more than 1,200 hp with a twin turbo Turbonetics turbo combination. |
