You won't go broke finishing off your project car with our 350 HO Turn-Key crate engine! It's packed with all the features you need to get a reliable 330 horsepower and 380 lb.-ft. of torque from a dependable, time-tested combination of Chevrolet Performance Parts. Of course, all the components used in this engine are brand new not remanufactured parts like the competition is trying to sell you. Designed by Chevrolet Performance's in-house engineers to give you maximum return for your hot rod dollar, the 350 HO Turn-Key is a great choice for your small-block crate engine needs.
The 350 HO is based on a tough, Chevy four-bolt block that holds a strong nodular iron crankshaft, good rods, and aluminum pistons. The high-lift camshaft gives the engine its own unique, aggressive idle. The cam is based on the same one found in 1965-67 Corvette 327 engines, but it has even more lift and duration.
