480 HP @ 5750 RPM, 475 lb-ft Torque @ 4500 RPM The hot new small-block V-8 in the GM lineup is the hyper-aggressive LS3. It offers a high-reving 376-cid combination that represents generations of small-block V-8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this, the engineers at GM Performance Parts offer you the LS376/480an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!


By combining traditional carbureted aspiration with the high-tech attributes of the LS platform, weve developed the ultimate modern engine for your vintage car or truckor race car.

The new combination is worth 515 horsepower at a stellar 6500 rpm and 469 lb-ft of grin-inducing torque at 5000 rpm.

They enable tremendous low-end torque and great high-rpm power. The LSX454 is delivered in Long block form. It also comes dressed with great-looking, all-new orange powder-coated valve covers with LSX454 logos engraved and painted black.
