Forget the rebuild – our best crate engine value comes with classic chrome style!
The 350/290 HP Deluxe combines Chevrolet Performance’s most popular crate engine with an aluminum intake manifold* and chrome dress-up kit to create one of the most stylish and value-driven engines on the market. The chrome dress-up parts include the valve covers (with push-in breathers and “T-bar”-style hold-downs), timing cover and air cleaner.

Like all of our crate engines, the 350/290 HP Deluxe starts with a brandnew block. And it’s a strong one, with four-bolt mains. It also includes a smooth hydraulic camshaft and durable aluminum pistons that deliver an 8.0:1 compression ratio. It’s a powerful, durable engine that makes a great alternative to rebuilding with your old two-bolt block.

Chevrolet Performance has all the parts you need to get your 350/290 HP engine running, too, from the starter and distributor to the plug wires and more. If you want even more power, our high-performance cylinder heads will take this stout Small-Block to the next level. 

* Chevrolet Performance recommends Holley 670-cfm carburetor P/N 19170092 for use with the 350/290 HP Deluxe
