From vintage hot rods to trusty farm trucks, the venerable Small Block Chevy engine, or SBC for short, has been the go-to engine swap choice for generations. And it all begins with a strong short block. Whether you’re building a classic Chevy 350 or a Stroker 383, you’ve got plenty of short block options to start with.

When shopping for a crate engine, a short block is often a popular choice because it typically only comes with the engine block and rotating assembly (including pistons, rods, crankshaft, etc.). That means you’re able to build your Small Block Chevy V8 the way you want it, adding your own cylinder heads, intake, carb/EFI, ignition, and more. And a short block is a particularly solid choice for the Small Block Chevy crowd simply because there is so much aftermarket support that you can take your SBC engine build in practically any direction you want.

From bullet-proof daily drivers to high-performance classic musclecars, you really can’t go wrong with a Small Block Chevy crate engine under the hood. And any quality Small Block Chevy engine build relies on a solid short block foundation—so find your SBC short block here now, at Summit Racing.
