Chevrolet Performance 350ci 290HP Crate Engine.

Chevrolet Performance 350 c.i.d. base engine assemblies are the most popular Chevrolet Performance crate engines because no one else can deliver as much performance for this kind of value. Chevrolet Performance believes that everyone should be able to afford a high quality GM V8 without going broke. Got a tired, old Chevy that needs a lift? Then these crate engines are just right for you. Chevrolet Performance 350 c.i.d. base engine assemblies start with a 4-bolt main bearing block, aluminum pistons, and a hydraulic camshaft. Then they're topped with cast-iron cylinder heads that are designed to be extremely durable, while still providing good airflow through the engine.
