  • Description:

    Don't bother repowering your trusty Big-Block-powered truck with a rebuild or reconditioned used engine. Our 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 our latestgeneration 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.
    Our 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 from Chevrolet Performance.
