Description
The S&S SH93 is a fully-assembled, turnkey 93-cubic-inch engine built specifically for 1970–84 Harley-Davidson big twins. If you’re restoring a classic or building a retro custom, this engine eliminates the guesswork of sourcing individual components—everything is engineered and tested to work together from day one. You get S&S’s reputation for reliability and performance without the fabrication headaches.
Built with a natural crankcase and black powder-coated cylinders, the SH93 delivers the aesthetic authenticity that vintage-focused builders demand, while its 8.5:1 compression ratio and hydraulic valve train with roller rockers ensure smooth, dependable operation across a wide rpm range. The included Super E carburetor and classic teardrop air cleaner complete the retro package—no custom intake sourcing required.
