Description

S&S Shovelhead Style 103″ Engine

Fitment Note: Fits shovel head frames.

• 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

• Although the engine life of a 103 is surprisingly good for a 5″ stroke motor, this is not a 50,000 mile engine there is a trade off- engine life for performance

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

• Engines Specifications are 3-5/8″ Bore, 5″ Stroke, 103″ Displacement, S&S Forged Piston Type, 10.7:1 Compression Ratio

• Covered by a 2- year parts and labor warranty.
