The Chevrolet Performance CT525 is a 6.2L LS3-based crate engine built for circle track racing, rated at 533 hp at 6,600 rpm and 477 lb-ft of torque at 5,200 rpm. It is aimed at Super Late Model competitors and similar racing series that need a sealed, high-revving aluminum powerplant out of the crate. This is a competition-only engine, not intended for street use, and it ships with anti-tampering seals for sanctioned circle track classes. Builders running the CT525 will find it slots into the broader Chevrolet Performance ecosystem of LS racing hardware we stock across our engines and components catalog.
Internally, the CT525 pairs a cast aluminum block with six-bolt cross-bolted main caps, a nodular iron crankshaft, powder metal connecting rods, and forged aluminum pistons that handle the engine's 6,700 rpm ceiling. Displacement comes in at 376 cubic inches with a 10.7:1 compression ratio, fed through high-flow rectangular-port LS3 cylinder heads with 68cc chambers. A hydraulic roller camshaft with .525-inch lift on both intake and exhaust drives the valvetrain, while coil-on-plug ignition and a 58X reluctor wheel manage spark. A 6-quart racing oil pan is shaped to clear GM rear-steer chassis, and the engine carries an internally balanced rotating assembly with a certified balancer. A 14-inch, 168-tooth automatic flexplate is included. Premium pump gas is the recommended fuel.
A racer dropping the CT525 into a Super Late Model chassis still needs to source the carburetor, starter, ignition controller (P/N 19355863), fuel system, exhaust, and front accessory drive separately, since the crate engine ships as a long-block package. The racing oil pan clears most rear-steer layouts, but verify your sump and pickup needs against your build before ordering supporting parts. We carry LS oiling hardware, timing components, and valvetrain parts to round out the assembly, including dedicated LS oil pans and oiling systems. Note this engine ships with no manufacturer warranty, consistent with circle track crate engine policy.

It uses forged aluminum pistons, a nodular iron crankshaft, and powder metal connecting rods inside a cast aluminum block with six-bolt cross-bolted main caps. The rotating assembly is internally balanced and topped with a certified balancer for sustained high-rpm racing duty.
The CT525 includes a 6-quart racing oil pan designed to clear GM rear-steer chassis layouts. Confirm clearance against your specific frame and steering setup before ordering supporting oiling components for your build.
