GM Performance Parts 502 HT Towing Engine

Product images may differ from actual product appearance.

The key to towing performance is torque, and the 502 HT has it way down low where it's needed most.

With 512 ft/lbs of torque at an incredibly low 3300 RPM and 377 horsepower at 4500 RPM, the 502 HT crate engine will help your vehicle climb hills, accelerate onto highways, and pass with confidence. The engine includes oil pan, valvetrain, valve covers, timing set, balancer, and externally-balanced 14" automatic transmission flexplate. For manual transmissions, use externally-balanced flywheel (#809-14096987) and 11" clutch assembly.
