    With the LSX Bowtie block, Chevrolet has built a 21st century 454 with the latest technology. It's lighter and more compact than an original Big-Block 454 - while delivering Big-Block output of 627 hp and 586 lb.-ft. - but 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 deep-breathing LSX six-bolt cylinder heads. It also comes dressed with great-looking, orange powder-coated valve covers with engraved ''LSX454'' logos.

    Chevrolet Performance delivers the engine without an intake manifold and other accessories. Use LSX-LS7 single plane carbureted intake manifold (p/n 809-19244033). 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 8-bolt crankshaft flange that may require an adapter for use with some transmissions.
