Description

Description for S&S Cycle SH103 SH Series engine

• This engine is based on the long standing 103 Shovelhead style Sidewinder kit, which has been in the S&S catalog since 1976

• The 103 is similar to our other Shovelhead style S&S engines, just bigger

• Features S&S Super Stock crankcases, S&S forged steel flywheels and connecting rods, S&S billet tappet guides with Evolution style S&S tappets, S&S Quickee pushrods, S&S billet rocker boxes, S&S forged roller rocker arms, and S&S 3-5/8" bore, engineering grade, cast iron, 3-5/8" bore cylinders with forged pistons

• Due to the displacement and compression ratio, an S&S Super 'G' carb and S&S dual-plugged heads come as standard equipment

• The 103 is only offered in 1970-84 Alternator style, and comes with the S&S Super Stock Ignition System

• The 103" Shovelhead style S&S engine is .300" taller than a stock Shovelhead, which means that it's not going to fit in a stock frame (Stock frames need to be modified to accommodate the extra engine height)

• To maximize engine life, all Shovelhead style S&S engines are built with the finest components, S&S forged steel connecting rods and flywheels are the industry standard for strength and durability

• High tensile cast iron cylinders are super strong and extremely wear resistant
