The convenience of a crate engine, the assurance of factory validate performance and the value of an inclusive package - that's what you get with Chevrolet Performance's Connect & Cruise crate powertrain systems. Each kit delivers a brand-new, fully assembled crate engine, a brand-new or remanufactured electronically controlled overdrive transmission, and the electronic transmission control module to get it all running in your project vehicle. Chevrolet Performance engineers matched the engines with their respective transmissions, ensuring they are up to the task of channeling big power with absolute dependability. The engine is traditional small block Chevy design that was a staple for decades in rear wheel drive production-vehicles. The connect & cruise systems' unique SuperMatic transmission controllers is designed to work with the carbureted engine for a seamless, "plug-and-play" installation that is quick, easy and intuitive. Detailed instructions outline all the necessary steps. The engineers did all the hard work of designing and calibrating perfectly matched powertrain systems - and they covered them with a 24-month/50,000-mile limited warranty.
SP350/385 Base Engine
Chevrolet Performance SP350/385 crate engine incorporates modern technologies such as a beehive-type valve springs to take the classic 350 Small-Block to new levels of high-rpm performance - without sacrificing the signature torque that has made it the benchmark of V-8 engines for nearly half a century. In fact, the 385 horsepower rating of the engine is complemented by excellent low-rpm torque, with the SP350/385 generating 405 lb.-ft. of torque at 3600 rpm. It's all due to the high-flow, lightweight aluminum cylinder heads. These heads are based on the proven 'Fast Burn' design, with large intake runners and 2.00/1.55-inch valves. The beehive valve springs enable greater high-rpm performance and durability, allowing the engine to rev higher to make the most of every cubic foot of air drawn through it. As with all of Chevrolet Performance's Small-Block crate engines, the SP350/385 is built with a cast-iron block with four-bolt main caps. It also features a forged steel crankshaft, an aggressive hydraulic roller camshaft and durable, high-silicon pistons. In this value-driven Base crate engine package, it also includes the intake manifold, distributor, water pump, damper and flexplate.
