Description

Quite simply the most powerful crate engine ever from Chevrolet Performance!

Drag racers take note! Chevrolet Performance's new LSX454R small-block V-8 crate engine delivers 750+ horsepower that will help you stay in front of the competition. More than the most powerful LS engine in our portfolio, it is the most powerful crate engine we've ever offered! Our engineers designed LSX454R for the unique, high-rpm demands of drag racing.

It is a high-compression, solid-roller combination that uses our new LSX DR cylinder heads. These 11-degree, six-bolt aluminum heads feature raised ports that provide tremendous airflow. We complement them with an exclusive, high-rise open-plenum intake manifold and a Dominator-type carburetor.

The LSX454R's bottom end includes our LSX Bowtie cylinder block and an all-forged rotating assembly. It's also worth noting that while we rate the engine at 750+ horsepower in its naturally aspirated form, it is capable of supporting nitrous and other power adders for even greater power.

Use the LSX454R as the centerpiece of a new racecar built with our 2012 Camaro body-in-white for the ultimate modern drag strip star. With 750+ horses under the hood, it will perform as good as it looks!
