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. The cylinders are longer then stock , so longer pushrods, and manifold must be used.","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":44535110467770,"sku":"SSC91-9031","price":2449.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/0855\/6218\/files\/ebf1ce75f645cd3b849e212e246a9a40_dc799cb6-f198-4732-95ce-2144f8bce614.png?v=1744609887","url":"https:\/\/performancemods.com\/products\/s-s-cycle-66-84-bt-93in-high-compression-3-5-8in-big-bore-cylinder-piston-kit-gloss-black-1","provider":"PERFORMANCE MODS","version":"1.0","type":"link"}
