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 brand-new 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 the Holley 670-cfm carburetor (P/N 19170092) for use with the 350/290 HP Deluxe.
