780+ horsepower in a box sounds good to me. GM Performance Parts makes dropping extreme horsepower in your truck easy with its latest creation—the LSX454R.
If you've ever taken a deep breath and let your lungs fill up on the fumes of race fuel, this new crate engine may be just what the doctor ordered for you. Designed to run off 100+ octane race gas, the LSX454R is rated at a very conservative 720hp, but we're hearing the test mules were making more like 780+. Not bad for 454ci and no power adder.
Featuring a forged rotating assembly, new hi-lift cam, and hi-rise intake, the real stars are the new cylinder heads with titanium valves that are flow-rated at over 430cfm on the intake side!
It's a real beast as GMPP is calling it their most powerful crate engine ever. All I can to do is be good the rest of the year and wait for Santa.
