Chevrolet Performance’s most economical Circle Track crate engine


Chevrolet Performance’s CT350 delivers 350 horsepower from a classic 350 cubic-inch combination. It’s just the thing budget-conscious racers can depend on for competitive performance and low-maintenance durability.


The CT350 is based on the popular 350 HO high-performance street crate engine, including a stout four-bolt main block and Vortec-style iron cylinder heads. The Vortec heads and unique dual-pattern camshaft offer pulling power that helps you hold a gear longer, keeping the engine in its sweet spot for quicker laps.


We complete the CT350 with an eight-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 at — and you’ll be ready to roll into the winner’s circle.
