The Chevy 454 short-block option, priced at $5,481.69, provides the same four-bolt main cast-iron engine block and rotating assembly as the $8,971.76 454HO complete crate engine option.

The Stock 454 delivered 522.5 lb-ft of torque at 4,750 rpm and 558.6 horsepower at 6,000 rpm. This means that the 454 outperformed the 383 in both horsepower and torque.
