GM Announces 720-horse LSX454R Racing Engine at PRI Show

By December 13, 2010

Follow me on:

LSX454R Among the many new products from GM Performance Parts announced this year's Performance Racing Industry (PRI) trade show, the big buzz was all about the LSX454R drag racing engine.

At 720 horsepower and 720 foot-pounds of torque, the LSX454R is the most powerful crate engine GM has ever offered for sale, and it's designed for the special rigors of high-performance drag racing. But the engine is so tremendously cool, I put together a detailed profile of the LSX454R for your drooling pleasure.

The LSX454R engine will be available early in 2011.
