A BIG-INCH ALTERNATIVE TO REBUILDING 

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 558 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.


INSTALLATION NOTES

  • • Requires the addition of carburetor, intake manifold, water pump, fuel pump, starter, distributor and ignition system (not included)

  • • Clutch linkage bosses are now drilled and tapped. When using cast-iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads, for clearance

  • • 502 engines now have a mechanical fuel pump boss!
  • • Comes with an externally balanced 14" automatic transmission flexplate. Use externally balanced flywheel P/N 14096987 and 11" clutch assembly for manual transmission applications
  • • Designed for pre-1976 street vehicles or any off-road vehicle
  • • Not intended for marine applications
