The versatile ZZ4 350 adapted for Circle Track competition
Renowned for its deep reserve of torque, responsive power, and great dependability, the ZZ4 350 crate engine is one of Chevrolet Performance’s most popular crate engines — and our engineers have adapted that combination as a winning, affordable racing engine in the CT355!
The CT355’s strength lies in its ZZ4 bottom end, which includes a block with four-bolt mains, a forged-steel crankshaft and high-silicon pistons. A steel hydraulic roller camshaft actuates valves in the high-flow aluminum ZZ4 heads, which boast 163-cc intake ports and 1.94/1.50-inch valves. This combination makes good power and great torque: 355 hp and 405 lb-ft.
Like our other Circle Track crate engines, the CT355 includes a racing oil pan with a dual kick-out design. It also includes a valve cover breather kit, a special “kool nut” rocker arm nut design, a dual-plane aluminum high-rise intake manifold, cast-iron water pump, HEI distributor, and balancer. You add the carburetor, starter, spark plugs, and wires — all available from chevroletperformance.com.
