High-RPM LS Performance with Forged Pistons


Chevrolet Performance’s deep-breathing, high-revving CT525 6.2L crate engine is assembled with strong forged pistons designed to support its performance capability and enhance its durability.


The CT525 is based on the LS engine family and 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. It’s a combination rated at 533 horsepower at 6,600 rpm and a strong 477 lb.-ft. of torque at 5,200 rpm, per Chevrolet Performance testing.


The engine assembly 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 LS/LSX ignition controller (P/N 19355863)—all available from Chevrolet Performance.

INSTALLATION NOTES

  • Use LS/LSX ignition controller P/N 19355863 (not included).
  • Requires addition of carburetor, starter, fuel system, exhaust system and front accessory drive system
  • The 6-quart circle track oil pan is designed to clear most GM rear-steer chassis with stock engine location
  • The engine is designed for circle track racing only. It is not intended for street use
  • The CT525 does not include a water pump or factory exhaust manifolds
  • Chevrolet Performance Circle Track racing engines include anti-tampering seals installed
