Current stock: 0

All GM Engines are currently on back order.

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. It is rated at 525 hp and 471 lb-ft of torque!

This 6.2L engine is similar to the LS3 V-8 that is standard in the Chevrolet Corvette, but it's been adapted to Circle Track Racing with a carburetor intake manifold, 6-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 the Chevrolet Performance LSX ignition controller P/N 19171130, which can be added as an option.
