LSX454 7.4L Chevy Performance Crate Engine

An LSX with Big Block Power!

With the Chevy LSX Bowtie block, we’ve 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 620 hp and 590 lb-ft of torque – but requires no more space under the hood than a production LS engine.

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

Chevy Performance delivers the LSX454 engine without an intake manifold and other accessories. Use 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 8-bolt crankshaft flange that may require an adapter for use with some transmissions.
