It boasts a 4.170-inch stroke and internal balancing, specifically designed to fit Ford SVO blocks.\n\nConstructed from forged 4340 steel, this crankshaft features a non-twist forging process, multi-stage heat treatment, and is stress-relieved and shot-peened for maximum strength and longevity. Each unit is rigorously tested with X-ray, magnaflux, and sonic inspection to guarantee top-tier quality. The design incorporates chamfered oil holes for superior lubrication, .125-inch fillet radii on rod and main journals to enhance structural integrity, and precision-ground, micro-polished journals to achieve a surface finish of less than 5 R.A. Furthermore, a target bob weight tolerance of +\/- 2 percent significantly reduces balancing labor.\n\nThis crankshaft is compatible with Small Block Ford engines, including the 289, 302, and 351W variants. It requires narrow bearings due to the .125-inch radius on the journals and supports both 1-piece and 2-piece rear main seal configurations.","brand":"Eagle Specialty Products","offers":[{"title":"Default Title","offer_id":52872905294136,"sku":"EAG435241706200","price":846.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/forged-4340-steel-crankshaft-4-170-inch-stroke","provider":"MOTORMIA","version":"1.0","type":"link"}
