CT350 602 Racing Crate Engine

19370602 Chevrolet Engine

Powerful, Durable and Affordable!

This Chevy race engine is designed for circle track use in the IMCA Sport Mod and Hobby Stock classes. It 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.

GM assembles the CT350 Sealed 602 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 as well as GM’s anti-tamper bolts to seal it up. IMCA seals added at our location to legalize it for IMCA Crate classes.

Engine ships with IMCA stamped seals installed.

This part replaces old P/N 19258602 and P/N 88869602.
