This 3-5/8" big bore kit may be used to replace the cylinders and pistons of an engine that has been upgraded with an S&S 93" Sidewinder® Kit with stock cylinder heads or an S&S V93 engine with S&S Performance Replacement heads. Stock crankcases must be bored to accomodate the 3-5/8" bore cylinders. The kit includes S&S 3-5/8" bore cylinders, 3-5/8" bore forged flat topped pistons with rings and wristpins, head gaskets, base gaskets, exhcaust gaskets, and instructions. Compression is 9.75:1. The cylinders shorter than stock, so shorter pushrods, and manifold must be used.
