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 base 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-inch/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 engines, the 350 HO Base is a great start to your engine needs as this long block is a great start to getting your project going.
