Powerful, Durable and Affordable!

Chevrolet Performance’s durable CT350 is the engine budget-conscious racers can depend on for race-winning performance and low maintenance!

350 hp @ 5,000 rpm / 390 lb.-ft. @ 3,800 rpm

It is based on the 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 390 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.

The CT350 arrives assembled with an 8-quart circle track racing oil pan, balancer, HEI distributor and an aluminum high-rise, dual-intake manifold. Add your carburetor, starter, spark plugs, wires and water pump – all available from Chevrolet Performance – and you’ll be ready for the starting line!

Also available with IMCA Stamped Seals installed which is required for certain classes of competition.
