SHOVELHEAD HARLEY REPLACEMENT ENGINE 93"

The SH103 is the largest production engine that S&S and Flathead Power™ offer for shovels. This engine features forged pistons with a compression ratio of 9.7:1, a Super G carb, and dual plugged heads. Unlike the SH93 and SH93H, the SH103 engine will not fit in a stock frame without modifications because the overall height of the engine is .300 inches taller than stock. This engine is recommended for high performance applications. This engine is not for everyone!

Shovels 93 Engines

SH93 engines feature forged pistons with a moderate compression ratio of 8.5:1 and a Super E carb. The SH93 is a good choice for daily riders, and is great for touring applications.

Shovels 93H Engines

SH93H engines are an excellent choice to replace a tired shovelhead engine, and boost performance at the same time. Modern features such as late style hydraulic valve train, polished billet rocker covers, forged roller rocker arms, and a single fire electronic ignition, combined with larger displacement, add up to a powerful and dependable engine package.
