Ford 428 with 4.125 stroke for 448 cubes. Pump gas, BBM heads, ported Streetmaster Edelbrock intake, hydraulic roller cam with 236 @.050 and .562 lift. Made 508 HP at 5600 RPM and 512 torque at 4600.
These are just some baseline pulls to prove out the mechanical stuff. No carb tuning was done at all since this engine will receive a conversion to EFI in the coming weeks with follow-up tuning.
