GM Big Block Crate Engines

Refine Results

Looking to upgrade your factory engine? Perhaps you're planning to build your own sports car or high-performance truck. Whether you're fixing your ride, restoring a classic one, or putting together a real competitor for motorsports, there are few choices better for it than a big-block crate engine.

What is a Crate Engine?

Crate engines are motors that have been fully or nearly fully assembled. They can sometimes be remanufactured, rebuilt, or even simply used, but most you'll find for sale online these days, especially those here at GM Wholesale Direct, are brand-new. What makes them "crate" is their inclusion of most or all of the engine parts you'll need for installation -- a block, rotating assembly, cylinder head, camshaft, air intake, carburetor, and others. What's this mean for an engine replacement or upgrade project? It makes the prospect a lot easier: for the most part, you don't have to build or rebuild anything, let alone, in your case, buy a bunch of individual big-block engine parts.

What Makes a Crate Engine "Big-Block"?

Big-block crate engines have larger bores than engines with small blocks. They make longer strokes, and they have bigger valves and ports. As a result, they're more powerful -- a boon for a serious street-riding or off-roading, for instance. What's most important to get right when shopping for these kinds of engines online, though? To order the genuine article, not something from an off-brand.

Why Buy a Genuine OEM Big-Block Crate Engine?

GM will have designed it to spec for what you drive, whether that's a Chevy pickup truck, one of the brand's many iconic sports cars, or otherwise. Aftermarket crate engines and parts can't always make the same compatibility guarantee.
