Lightweight, High-RPM LS Power!
Chevrolet Performance’s deep-breathing, high-revving CT525 6.2L crate engine is based on the LS engine family
and delivers serious power for serious racing series, including Super Late Model and modifieds.
It is similar to the 6.2L LS3, but we’ve 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-?ow LS3 rectangular-port cylinder heads. This combination produces 533 hp at 6,600 rpm and a
hefty 477 lb.-ft. of torque at 5,200 rpm.
The CT525 6.2L comes with coil-on-plug ignition, and an SFI-certified balancer. All that’s needed to complete
the assembly is a carburetor, wanter pump, exhaust manifolds, starter and our LSX ignition controller P/N 19171130 – all available from CrateEngineDepot.com.
