The Chevrolet Performance CT350, more often known as the 602 crate, is the go-to choice for racers because it fits the rules for many classes or simply makes sense for the budget. While built motors can offer more power, they often come with twice the cost. The 602 crate, at 350 hp, delivers dependable, consistent, proven performance with more than enough torque to keep you competitive. Its four-bolt main block, iron Vortex heads, and broad torque curve-peaking at 396 lb-ft--give you solid pull without breaking the bank. You get race-ready components, proven reliability, and a package that's ready to run-so you can stay on track while others are still sinking dollars into expensive builds.
