HIGH-RPM PERFORMANCE WITH NEW FORGED PISTONS!

Chevrolet Performances deep-breathing, high-revving CT525 6.2L crate engine is upgraded with forged pistons designed to support its performance and enhance its durability.

The CT525 is based on the LS engine family and is similar to the 6.2L LS3, but weve adapted it to circle track racing with a carbureted intake manifold, 6-quart racing oil pan and more. The engine is lightweight and strong, using an aluminum block with cross-bolted 6-bolt main caps and high-flow LS3 rectangular-port cylinder heads. This combination is rated 533 hp at 6,600 rpm and a hefty 477 lb.-ft. of torque at 5,200 rpm, per Chevrolet Performance testing.

The CT525 6.2L comes with coil-on-plug ignition and an SFI-certified balancer. All thats needed to complete the assembly is a carburetor, starter and our LS/LSX ignition controller (P/N 19355863)all available from Chevrolet Performance.
