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 96" Hot Set Up Kit® with stock cylinder heads. This kit may also be used to upgrade an engine with an S&S 89" stock bore stroker kit to 96". Stock crankcases must be bored to accomodate the 3-5/8" bore cylinders, but the 4-5/8" stroker flywheel assembly does not need to be rebalanced. 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 are nearly stock length, so stock length pushrods, and manifold may be used. Stock cases will need to be bored out to 3 5/8".
- Cylinders are constructed from premium aluminum castings with cast-in iron liners
- Kits include cylinders, pistons, rings and gaskets (head, base and exhaust)
- Made in the U.S.A.
- This project requires a skilled technician. It is the responsibility of the person assembling the parts to check all clearances and assembly specifications.
- Requires crankcase boring for installation.
NOTE: Crankcases must be bored to accept the larger 3-5/8" cylinders EFI systems must be recalibrated
