Info
The Chevrolet Performance CT350 circle track crate engine delivers competitive and durable power at an economical price! 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.
The 602 crate engine is delivered complete from the oil pan to the intake manifold – including an HEI distributor – 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!
