LS3 Based Racing Engine is a Lightweight Powerhouse!

Free Shipping!

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 533 hp and 477 ft/lbs of torque!

This 6.2L engine is similar to the LS3 V-8 that is standard in the Chevrolet Corvette, but they have adapted it 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 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

NOTE: For 2016, the CT525 does not include water pump or factory exhaust manifolds.
