CT350 IMCA-Sealed 602 Crate Engine, Dyno Tested, Dressed

The Chevrolet Performance CT350 circle track crate engine delivers competitive and durable power at an economical price, and now Speedway Motors Racing Engines is offering them as a dressed & dyno-verified package that is ready to race! Designed for circle track's weekend warriors, this bullet-proof 350-horsepower, 350-cubic-inch IMCA-sealed racing crate engine (often referred to as the "602 crate") is a tough combination of power and reliability – and it fits almost any racing budget.

Based on GM Performance Parts' popular 350 HO engine, including a brand-new, four-bolt-main block, 9:1 hypereutectic pistons, cast iron crankshaft and GM iron Vortec cylinder heads, the 350/350 Factory Stock version features a high-rise dual-plane intake manifold, 8-quart single kick-out circle track oil pan, valve cover kit with breather tube and breather, and special "kool nut" rocker arm nut design. The 350 HO's unique dual-pattern cam is included, too. It's based on the one found in 1965-67 Corvette 327 engines, but with more lift and duration to clear the engine exhaust quickly and move in more air – providing excellent mid- and high-range power, where you need it on the track.

This dressed 602 crate engine is delivered complete from the oil pan to the intake manifold – including an HEI distributor, spark plugs & wires. The 350/350 CT350 racing crate engine has the proven parts and horsepower to enable a competitive racecar. Getting it into the winner's circle, however, is your job!
