The LSX454R crate engine is the most powerful crate engine ever from Chevrolet. How does that grab your attention? It is rated at 720 horsepower and 720 pound feet of torque, and wasn’t designed to do anything other than sprint 1,320 feet from a dead stop as quickly as possible. Chevy Performance uses the tall-deck LSX Bow Tie block as the foundation, and makes 454 cubic inches with a 4.185” bore and 4.125” stroke all forged rotating assembly. A set of fully CNC’ed LSX-DR cylinder heads and a solid roller cam with 0.738” lift and 250/270 duration move the air, and the whole combo is topped off with the legendary Holley 4500 Dominator.
It's hard to believe that a 'crate engine' could produce a wheelie and an ET like that. Of course, the 150 shot does its part too...
The wheel-standing 1967 Camaro you see in the video above is powered by one of these LSX454R crates, and belongs to Peter Forcellini from Canada. Forcellini left the long block alone, but threw in an additional 150 shot of nitrous to take full advantage of the LSX’s strength. The result is an E.T. of 8.95 at 150 MPH. As good as that is, Forcellini tells us that he’s already started the hunt for more nitrous fed horsepower from the LSX545R. “I went to a lot of trouble to get my hands on the LSX454R, but I just took the engine back out and stripped it,” says Forcellini. “I’m modifying it to run in OSCA’s EZ Street class this season in the same Camaro. I want it to make around 1,500 horsepower on nitrous with 7.5s as my ET target. CFE will be building a sheet metal intake for split Dominators, and I have a few other things in the works.” We’ll definitely be paying attention to the OSCA this year to see how well Forcellini’s Camaro performs with the new combo.

Up to 720 horsepower in a box - it's truly a thing of beauty...
