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.

PRODUCTS ON OUR SITE should be viewed as a Catalog of Genuine GM OEM Auto Parts & Accessories. They are subject to availability and may be discontinued or have a superseded number without us having been updated by the manufacturer.
Some Parts are “On-Hand” or “in-stock” and come from our physical location. Others are sourced from our direct GM suppliers. On occasion, some items become unavailable or are understocked without our knowledge. GM provides us with updates continually, but this is not always reflected immediately on our store site.
We make every effort to communicate with you via email regarding any questions, updates or changes about your order throughout the process. If an item cannot be supplied, you will not be charged or a refund will be applied for that particular part or order as needed.
Shipping prices quoted on your final order may be subject to change based on actual packaging box size + delivery logistics. The dimensions x weight seen on a product page is for the actual part or accessory itself, not necessarily the packaging box used. This can affect the later shipping rate calculations. We make every effort to give you the best rate on your order and will consult with you on changes.
Orders with a VIN number provided are recommended and verified for accuracy.
Any illustration is a simple rendition of the part and where it is located on the vehicle; it is for reference only. Factors such as trim, color, and options are not depicted in the illustrations. Check with us if a part or accessory stock photo shows a color style to make sure what is ordered will be that color.
