Product Details
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 our new 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 LSX 454 is delivered in long block form. It also comes dressed with great looking, all new orange powder-coated valve covers with 'LSX 454" logos engraved and painted in black.
Note:
Oil pan and oil pump pickup are not included. LSX valve covers do not have coil mount provisions, coils will need to be relocated
