Fits On/Installation Notes:

This GM Performance big block 454 HO is an awesome value, ready for an easy transplant into your classic muscle car or street rod! It is a Gen VI-based block with a conventional-style mechanical fuel pump boss, and it sounds much like the performance big blocks of the 1960s. The engine has a windage tray, one-piece rear main seal, and high-speed single roller timing chain. An 8.75:1 compression ratio means you've got an engine that's satisfied on today's premium fuel with no appetite for lead, octane boosters, or other fuel additives.

The sturdy foundation of the 454 HO
is the starting point of a custom en-
gine build. Use externally balanced
flywheel for manual transmission

If you want the strength and convenience of the 454 HO bottom end,
but want to add your own heads and induction system, use our 454
Partial engine P/N 12498778.
