LSX - Series Crate Engines

Race-Engineered Performance for the Street or Strip
Chevrolet Performance’s LSX crate engines take LS power to the next level, with racing-engineered combinations that deliver power with strength. Each is based on the high-performance LSX Bowtie block, which is designed to support extreme performance combinations, including supercharging, turbocharging and nitrous.

Chevrolet Performance’s LSX376 B-8 and LSX376 B-15 engines are specially designed for the high-pressure demands of forced induction, with forged crankshafts and pistons. Our cylinder heads complement that tough block with tremendous airflow and six-bolts-per-cylinder clamping strength that supports power adders of all types. The LSX454R is the biggest, baddest LS engine in Chevrolet Performance’s arsenal. It’s a 750-horsepower, naturally aspirated drag strip assault weapon that’s capable of propelling your race car down the track in 9 seconds or less. If your car can handle the power, the LSX454R will help you win! When big LS power is what you need, turn to Chevrolet Performance. Nobody does ultimate-performance LSX crate engines like us.
