350 HO TURN-KEY - 330HP

From air cleaner to oil pan, this affordable and powerful 350 comes with it all

The classic 350 Small-Block engine has powered countless project cars since its introduction in the 1967 Camaro and it is easy to understand why: it makes great power and torque in a compact, affordable package. That’s exactly what you get in our 350 HO Turn-Key crate engine.

Construction begins with a brand-new engine block with four-bolt mains, which delivers greater strength than that old two-bolt block you were thinking of rebuilding. We also add a set of brand-new Vortec iron heads and a hydraulic flat-tappet camshaft with 0.435/0.460-inch lift specs. It gives the engine the idle quality of a true muscle car without the need
for periodic lash adjustments.

As one of Chevrolet Performance’s Turn-Key engines, the 350 HO Turn Key comes with the intake manifold and distributor installed. It also includes the carburetor, front-accessory kit, starter, fuel pump and spark plug wires. It’s just about everything you need to get this classic 350 up and running in your project vehicle.
