  • OUR BEST CRATE ENGINE VALUE DELIVERS ALL YOU EXPECT IN A POWERFUL SMALL-BLOCK!
    The most affordable Cheverolet Performance Small-Block crate engine is also our best seller - and it's easy to understand why. The 350/290 Base Small-BIock features four-bolt mains for strength and makes a great economical alternative to rebuilding a tired, two-bolt main core. Use it to re-power your daily driver or drop it in your budget Camaro project!
    Inside the 350/290 Base are quality parts, including a camshaft and durable aluminum pistons that squeeze an 8.5:1 compression ratio. We offer the 350/290 in a base form, allowing you to add the induction and other accessories. That's great for builders swapping over the intake manifold, carburetor and other components when re-powering a vehicle.
    Chevrolet Performance has all the components to build up the 350/290 Base into a high-performance, great-looking street engine, too - from an aluminum intake and carburetor (we recommend the 670-cfm Holley four-barrel, P/N 19170092) to the distributor, water pump and more. Save the time and hassle of rebuilding your old engine by ordering the 350/290 Base and finishing it to your own specifications.
