An engine with 454 cubic inches will always be associated with higher performance Chevys, and that tradition continues with the all new LSX454 crate engine. We started with the new LSX bowtie block, stuffed it with an all-forged, super tough rotating assembly, and bolted on a pair of new GM deep breathing LSX six-bolt cylinder heads.
The new LSX six bolt cylinder heads are based on the race-derived LS7 heads that help deliver more than 500 horsepower in the Corvette Z06. The Pace LSX 454 is delivered fully assembled with engine controller and harness.
Keeping with the LS tradition, this LSX454 requires no more space under the hood than production LS engines.
