SH-Series Engines<br />
For 1966-’99 Chassis<br />
Flathead Power SH-Series engines are an excellent choice to replace a tired shovelhead engine, and<br />
boost performance at the same time. Modern features such as late style hydraulic valve train, polished<br />
billet rocker covers, forged roller rocker arms and a single fire electronic ignition – combined with<br />
larger displacement – add up to a powerful and dependable engine package. Available in 93", 93"<br />
high compression, and 103" versions. High compression 93" and 103" engines come standard with<br />
dual plugged heads. Generator versions come with S&S polished billet timer and period correct flat<br />
side gearcover. Available with 1966-'69 style generator, 1970-’99 alternator, and custom alternator/<br />
generator crankcases.<br />
<strong>1926</strong>-<strong>1984</strong> <strong>Vintage</strong> <strong>Models</strong><br />

engines for shovelheads have<br />
many modern features that make<br />
them more durable as well as more<br />
powerful than stock.<br />

The generator shovelhead engine<br />
replaced the panhead engine in 1966,<br />
and was only produced through 1969.<br />
Although S&S generator engines have<br />
the classic stock appearance, the increased<br />
performance and the modern<br />
technology built into each one make<br />
them the obvious choice for upgrading<br />
performance in stock bikes.<br />

The dyno chart above compares the performance of the SH93, SH93H, and SH103 engines.<br />
The SH93 engine’s excellent midrange torque and great engine life makes it ideal for most<br />
applications, including touring. The SH93H makes about the same torque up to about 3500<br />
rpm, but the higher compression and more aggressive cam provides higher rpm torque and<br />
horsepower. The SH103 has more of everything, except engine life. Nothin’s for nothin’!<br />
