Chevy 350 HO Turn-Key Crate Engine

Budget builders will appreciate the GMPP 350 HO Turn-Key crate engine. It's ready to go! Packed with new quality GM Performance parts and built with the same quality that GMPP always provides, you'll be able to save come cash and get great performance from the 350 HO turn-key engine.

This isn't just any basic crate engine. Built on a Chevy 4 bolt main block with a nodular iron crank, quality rods and aluminum pistons, this engine is a bit of a beast that is perfect for a rebuild of a street car or truck. Also inside, a high lift cam bumps the valves for an aggressive idle, but still streetable. Duration and lift numbers on this cam are slightly more than the famous 65-67 Vette 327 engines.

This crate engine is ready to romp as it is fully assembled and just needs installed. The 350 HO Turn-Key engine comes with an accessory drive package, fuel pump, starter, and spark plug wires included in the package (not installed). Turn-Key engines require some assembly, but it is minimal and basic.
