About this part

Product Details

S&S Cycle is well-known for building high-performance V-twin motorcycle engines and components. If you're looking to replace a tired stock engine in your 1984-1999 Big Twin motorcycle, this all-new S&S V80 Long Block Engine is a substantial upgrade that will give you a lot more power.

This isn't a rebuild; it's a completely new engine built with premium S&S components. It features specially machined cylinder heads that accept stock-length manifolds, allowing you to use your existing carburetor and air cleaner setup, though re-jetting will be required. The engine also includes S&S cylinder heads, S&S 585 valve springs, and forged rocker arms for improved performance. While the fuel and ignition systems are not included, you can use your current aftermarket ignition and carburetor for a cost-effective installation. This engine is EFI compatible, but will require calibration with an aftermarket module or add-on tuner.

Choosing a new S&S engine over a rebuild can save you time and deliver a significant power increase. This engine is made in the USA and comes with a two-year warranty. Please note that this engine is not CARB approved and cannot be shipped to California.
