CT525 6.2L Circle Track Racing Crate Engine
19432720 Chevrolet Motor
Lightweight, High-RPM LS Power!
The deep-breathing, high-revving Chevrolet Performance 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 GM 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-flow 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, starter and our LSX ignition controller P/N 19171130 ? all available from Chevrolet Performance.
