Details

• Product ID: 12568774
• Description:

  This Chevrolet Performance Parts 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.
