Here's what I need to know to help you:
* What vehicle was the engine in? (e.g. Chevy Silverado, C/K Pickup, Suburban, Corvette, etc.)
* Was it a standard 454 or a 454 with a specific package or code? (e.g. "454 HO", "454 TBI", etc.)
Once you give me that information, I can provide you with the correct horsepower rating.
