Chevrolet Performance HT502 502ci/377HP Truck Engine

An Affordable, Big-Inch Alternative to Rebuilding

Free Shipping!

Don't bother repowering your trusty Big-Block-powered truck with a rebuild or reconditioned used engine. Chevrolet Performance HT502 crate engine is an affordable alternative with more power and greater durability, including a whopping 541 lb.-ft. of trailer-tugging torque. That's more than the factory ever offered and more than you'll get with a stock-type rebuild.

It is uniquely suited to pre-1978 trucks, but is adaptable to a variety of applications, and it's built with the latest-generation block casting with four-bolt main caps. An all-forged rotating assembly delivers exceptional strength and durability, while a mild 8.75:1 compression ratio is suitable for regular pump gasoline at all altitudes and engine loads.

This assembly comes with the heads and a balancer installed. An induction system, ignition, starter, water pump and other accessories are required to finish the engine. All necessary components are available, here at JEGS.com or you can give one of our technical specialist a call at 1-800-345-4545.
