350 HO Turn-Key - A 350 that’s been stepped up in power

You won’t go broke finishing off your project car with a GM Performance Parts 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 GM Performance Parts. Of course, all of the GM Performance components used in this engine are brand new—not remanufactured parts like the competition is trying to sell you. Designed by our in-house engineers to give you maximum return for your hot rod dollar, the GM Performance 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 crate engine 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.

Complete from top to bottom, the 350 HO comes pre-assembled with the intake manifold, carburetor, water pump, and distributor. With the Turn-Key trim level, you also get everything you need for a complete, running engine right out of the crate. We ship it with an accessory drive package, fuel pump, starter, and spark plug wires included in the package (not installed). The 350 HO Turn-Key Chevy crate engine offers you an incredible performance value—all you need to do is add the fuel and enjoy!
