The Chevrolet 454 engine is a large-displacement, naturally aspirated, 90-degree, overhead valve, gasoline-powered V8 engine produced by the Chevrolet Division of General Motors. It's part of the "big-block" engine family that has powered numerous GM vehicles from the late 1950s to the present. First introduced in 1970, the 454 quickly became known for its impressive horsepower and torque output. In its initial years, it was available in models like the Chevrolet Caprice, Chevelle, Monte Carlo, El Camino, and Corvette. The engine is designed for power and built to last.
The original 1970 LS6 version of the 454 produced 450 hp and 500 lb-ft of torque. Later versions, introduced in the 1990s, featured electronic fuel injection (EFI) and produced between 230 to 255 hp. The modern 454 HO crate engine generates around 438 horsepower and 500 lb-ft of torque. Crate engine versions of the Chevy 454 are still available. Depending on the configuration and performance level, prices for 454 crate engines can range from approximately $5,195 to upwards of $14,000. Availability varies, with some in stock and others requiring vendor order.
