Give your ride some serious power with these ATK High Performance GM 454 500HP Stage 1 crate engines. These engines are built from the ground up to be tough, reliable, and powerful, just like a big block should be. ATK builds each of these mills to the highest quality and makes them kick out 500 hp and 550 ft.-lbs. of asphalt-shredding torque.

These ATK High Performance GM 454 500HP Stage 1 crate engines include the following:

* Handpicked, remanufactured block
* Performance aluminum cylinder heads
* OE crankshaft and connecting rods
* Hypereutectic pistons
* Hydraulic flat tappet camshaft
* Cam lift- .540 int./.540 exh.
* Cam duration @ 0.50- 228 int./238 exh.
* 10.0:1 compression
* Valve covers
* Timing cover and timing set
* Oil pan, pump, and pickup tube

All horsepower and torque numbers advertised on our website are provided by the crate engine manufacturer. These numbers were achieved on a professionally operated dynamometer to compensate for variables like altitude, temperature, relative humidity, vapor pressure, and barometric pressure, all of which impact measured horsepower and torque. If you do not purchase a complete crate engine, the selection of additional components, and how those components are tuned, will have an impact on measured horsepower and torque. Ignition and fuel system components, as well as the fuel octane and quality of the fuel that you select, will impact the numbers. Please understand that, while horsepower and torque numbers are repeatable within reason, they will most likely not be reproduced identically.
