Our Budget Big-Block Performer!


Chevrolet Performance’s 454 HO crate engine offers strong Big-Block torque 500 lb.-ft. to fit almost any builder’s budget. The foundation is a brandnew, updated cylinder block, which incorporates many strength and performance design enhancements to make it a smart and economical alternative to rebuilding.


We also added an all-forged reciprocating assembly for greater durability, a roller camshaft that optimizes performance and a set of deep-breathing rectangularport iron cylinder heads. The 454 HO is delivered with a water pump, balancer, 14-inch flexplate and aluminum intake manifold. Add a carburetor, ignition system and starter and your budget Big-Block will be ready to roar. All of the necessary parts are available from Chevrolet Performance.


INSTALLATION NOTES

  • Requires addition of carburetor, starter, fuel pump, 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
  • Comes with an externally balanced 14" automatic transmission flexplate; use flywheel P/N 14096987 and 11" clutch assembly for manual transmission applications
  • Not intended for marine applications
