S&S, 93" Shovelhead Sidewinder kit

70-84 Shovel (NU)

Gloss black finished cylinders. Complete kit, incl. 4-1/2" stroke flywheel assembly, to transform your stock 74" or 80" Shovel into a 93" Big Bore Stroker motor with 3-5/8 bore x 4-1/2" stroke. Cylinders are +.075" taller. Moderate 8.5:1CR and forged pistons will give almost stock-like engine life. S&S advises a Super E carburetor kit or simular for best allround performance. Note: This kit requires a special manifold to compensate for the increased cylinder length. The appropriate S&S manifold must be ordered separately. For manifolds see: 940342 Super E. for 66-78 Shovel with O-ring type heads. 940358 Super E, for 79-84 Shovel with Band type heads. 940343 Super G, for 66-78 Shovel with O-ring type heads. 940359 Super G, for 79-84 Shovel with Band type heads.
