Description

When it comes to repowering your trusted Big-Block-powered pulling truck, don’t bother with the time it takes for rebuilding, when Chevrolet Performance’s HT502 offers an affordable, durable and powerful alternative.

It is built with a brand-new, latest-generation cylinder block with four-bolt main caps and features an all-forged rotating assembly for strength. A mild 8.75:1 compression ratio also makes it suitable for pump gas at all elevations. The 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 of the 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! (NOTE: There is NO fuel pump lobe behind the 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
  • Not intended for marine applications
