New Connect and Cruise Package

This New Pace Performance Connect-and-Cruise package combines late model engine technology with old school gear banging fun.

Pace Exclusive LSX 454 585HP with LS7 EFI Crate Engine

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. They enable tremendous low end torque and great high RPM power. The Pace LSX 454 is delivered fully assembled with engine controller and harness. It also comes dressed with great looking, all new orange powder-coated valve covers with "LSX 454" logos engraved and painted in black.

Keeping with the LS tradition, this LSX454 requires no more space under the hood than production LS engines.

Note: this engine has the ignition coils mounted on the valve covers.
