Lenny Moore's Butler Performance 499 cu.in Pontiac Pull Truck Engine - 820 HP with Factory Cast Iron RAIV Heads !!

Butler Performance built the first engine for Lenny Moore's GMC pull truck almost 10 years ago. It was a 474 cu.in Engine with a 455 block and ported RAIV heads. Lenny won multiple championships with that engine and it is still running strong today! A typical pull lasts for over 20 seconds with the engine running at over 7500 RPM !!

Lenny's second and current engine (pictured) is a Butler Performance 499 cu.in. with an IAII block. This engine features highly modified (by Butler Performance) RAIV heads. We have converted these one of a kind heads to a "wideport" configuration that utilize the same .700" offset T&D shaft rockers as our CNC Wideport Edel. heads. These heads will allow Lenny to sustain higher RPM and wheel speed through the duration of the pull. We used a BOP 1x4 intake and 1150 Carb. 820 HP @ 6800 RPM- 650 ft.lbs. of torque. ( 4.375" Bore x 4.150" stroke ) Butler Performance has a PONTIAC Engine combination for ANY application!
