Description
Approved for the Pro Sprint Class at Knoxville Raceway this competition deep-breathing, high-revving CT525 6.2L crate engine is upgraded with forged aluminum pistons designed to support its performance and enhance its durability. It is based on the LS engine family and delivers serious power for serious racing series, including Super Late Model and Modifieds.
The engine family commonly called the LS series debuted in 1997. General Motors called it the Gen-III Small-Block, with the iron-block versions in trucks and the all-aluminum LS1 introduced in the then-new C5 Corvette. GM has continued to refer to its modern V-8 engine family as Gen III and Gen IV, but to the enthusiasts who quickly grasped the tremendous performance potential of the engines, every engine of the platform is nicknamed “LS.”
Chevrolet Performance is committed to providing proven, innovative performance technology that is truly…. more than just power. Chevrolet Performance Parts are engineered, developed and tested to exceed your expectations for fit and function.
The CT525 is based on the 6.2L LS3, but Chevrolet Performance has adapted it to circle track racing with a carbureted intake manifold, a high-lift roller camshaft, 6-quart racing oil pan and more.
