Big-Block performance built from our LSX Small-Block

One of the most legendary engines in muscle-car history was the Chevy 454 Big-Block. With the LSX Bowtie block, Chevrolet Performance engineers were able to build a 21st century 454 with the latest technology — and it requires no more space under the hood than a production LS engine.

The LSX454 is filled with an all-forged, super-tough rotating assembly and features a pair of our new, deep-breathing LSX six-bolt cylinder heads. It also comes dressed with great-looking, orange powder-coated valve covers with engraved LSX454 logos.

We deliver the LSX454 without an intake manifold and other accessories. Use the LSX-LS7 single-plane carbureted intake manifold (P/N 19244033). The LSX454 valve covers do not include provisions for mounting ignition coil brackets.  Aftermarket or custom relocation brackets must be obtained. It also includes an eight-bolt crankshaft flange that may require an adapter for use with some transmissions.
