Product Overview
Brand New! Not used!
One of the most legendary engines in muscle car history is the Chevy 454 Big-Block. With the LSX Bowtie block, GM Performance Parts 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. It’s
perfect as the power plant for a late-model Camaro drag car or a high-tech retro-fit for a ’70 Chevelle pro-touring machine.
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, all-new orange powder-coated valve covers with engraved “LSX454” logos. GMPP delivers the LSX454 without an intake manifold and other accessories. With a carburetor and high-flow GM Performance Parts intake manifold, the LSX454 is good for about 620 horsepower and 600 lb-ft of torque —or about 580 hp and 600 lb-ft. with fuel injection.
NOTE: Due to the number of application variations, the LSX454 crate engine does not include an oil pan. See the LS Engine Components section for production-style oil pan choices. Also, the LSX454 valve covers do not include provisions for mounting the ignition coil brackets. Aftermarket or custom relocation brackets must be sourced.
