Longtime friend and customer Mike Leech Dyno tested his Pontiac engine this month, and the results are impressive! Mike’s 554CID Monster ripped to 8400RPM to make 1137HP on BES’ engine dyno. Great Job Mike! The engine is topped by a set of Edelbrock Wide Port RPM heads massaged to the limit by John Marcella of Marcella Manifolds, as well as a cast intake prepped by John. Here is a rundown of the combo:
- All Pontiac iron block
- 4.600 Stroke x 4.380 Bore
- Custom MGP Aluminum Rods
- Custom CP Pistons
- Total Seal Rings
