Circle Track Crate Engines - CT350

Chevrolet Performance’s durable CT350 is the budget-conscious crate engine racers can depend on for competitive performance and low maintenance and with 350 horsepower, it’s the perfect match for many short-track series.

The CT350 is based on our popular 350 HO high-performance street-class crate engine and features a strong four-bolt-main block and iron Vortec cylinder heads. A unique dual-pattern camshaft helps deliver almost 400 lb.-ft. of torque between 2,000 and 5,500 rpm peaking at 396 lb.-ft. at 3,800 rpm.

With that much pulling power, you can hold a gear longer, keeping the engine in its sweet spot for quicker laps. We assemble the CT350 with an 8-quart circle track racing oil pan, balancer, HEI distributor and an aluminum high-rise, dual-plane intake manifold. Add your carburetor, starter, wires and water pump—all available from Chevrolet Performance and you’ll be ready for the green flag
