Chevrolet Performance’s CT525 6.2L crate engine is based on the latest-generation LS engine family and delivers serious power for serious racing series, including Super Late Model and similar classes. It is rated at 533 hp and 477 lb-ft of torque.
This 6.2L engine is similar to the LS3 V-8 that is standard in the Chevrolet Corvette, but we’ve adapted it to Circle Track racing with a carburetor intake manifold, six-quart racing oil pan, and more. The engine is lightweight and strong, using an aluminum block with cross-bolted six-bolt main caps and high-flow LS3 rectangular-port cylinder heads.
The CT525 6.2L comes with coil-on-plug ignition, a water pump, exhaust manifolds and an SFI-certified balancer. It also comes with a 14-inch/168-tooth automatic transmission flexplate. All that’s needed to complete the assembly is a carburetor, starter, and our LSX ignition controller, P/N 19171130. All the necessary parts are available online at chevroletperformance.com.
