This kit may also be used to upgrade an engine with an S\u0026amp;S 84\" stock bore stroker kit to 93\". Stock crankcases must be bored to accomodate the 3-5\/8\" bore cylinders, but the 4-1\/2\" stroker flywheel assembly does not need to be rebalanced. The kit includes S\u0026amp;S 3-5\/8\" bore cylinders, 3-5\/8\" bore forged pistons with rings and wristpins, head gaskets, base gaskets, exhaust gaskets, and instructions. Compression is 9.1:1.
