Chevrolet Performance’s durable CT350 is the engine budget-conscious racers can depend on for competitive performance and low maintenance. At 350 hp, it is a perfect fit for a large number of short track racers.

It is based on our popular 350 HO high-performance street crate engine and features a strong four-bolt-main block and iron Vortec cylinder heads. A unique dual-pattern camshaft helps deliver more than 300 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, spark plugs, wires and water pump – all available from Chevrolet Performance – and you’ll be ready for the green flag!
