{"product_id":"boss-302-engine-block","title":"BOSS 302 Engine Block","description":"Unleash legendary power with the Ford Performance BOSS 302 Engine Block, expertly crafted by Ford Performance Engineers for unmatched strength and versatility. Ford Performance Engineers have designed this replacement for the legendary BOSS 302 and 351 blocks, using the latest technology and manufacturing techniques from both the production and racing worlds. The BOSS block's capability has been proven worldwide, both on the track and on the street.\n\nBy preserving many of the dimensions and features from the original 289-351 blocks, the BOSS blocks are compatible as replacements for use in just about any vehicle that used a Windsor style engine. Cast from diesel grade iron and designed with added material in key areas, the BOSS block strength is far superior to any Ford OE block ever produced. It features a 4.125\" bore capacity, finished at 3.990\" to 3.995\" rough bore, and an 8.2\" deck height finished at 8.200\" plus .010\" to .015\". The block is designed with optimized cylinder wall length for stroker applications up to 3.5\" with no grinding or clearancing (depending on crank\/rod manufacturer).\n\nKey construction details include splayed 4-bolt main on 2, 3, and 4 main caps, with 2-bolt mains on the first and fifth main caps. Main bearing bores are finished to the low limit, and lifter bores are also finished. It is machined to accept factory roller lifter guides and lifter guide retainers. The block fits a factory 1979-1995 Mustang oil pan with a custom oil pickup tube (part number M-6622-BOSS302). Additional features include NASCAR-inspired front oil feed on both lifter galleys, revised cooling system passageways, Siamese bores with drilled coolant crossover holes (except on M-6010-B302BB), and increased bulkhead material. It uses threaded core and galley plugs with straight thread port plugs with O-ring. Special length 1\/2\" head bolts or head studs are recommended with specific cylinder heads (M-6065-BOSS or M-6014-BOSS are recommended with M-6049-X306\/X307\/X2\/Z304DA\/Z2 heads). The block is designed for use with X306, X307, X2, C3, D3, Z304DA, Z2, and GT40P cylinder heads. It is not designed for Production 302\/351W (though GT40P is compatible), M-6049-Y302, Y303, X302, X303, X304, or X305 heads. It uses common OD cam bearings (M-6261-J351 \/ R351) and includes a unique cam plug (M-6026-S351). Head gasket M-6051-S331 or M-6051-CP331 is recommended. The block is designed to be compatible with vehicles equipped with the original 302 and 351W block and uses a stock-type timing cover (M-6059-D351 recommended, includes fuel pump provision). It fits a factory Mustang oil pan with a custom oil pick-up tube (M-6622-BOSS302). A Service Replacement Plug and Dowel Kit (M-6026-A) is available separately and includes O-ring threaded plugs for oil galleys, water drains, and core holes, along with dowels for the front cover, clutch housing, and cylinder heads. The block retains the clutch cross shaft pivot hole, features original style oil filter location, original motor mount boss locations, and original bell housing pattern. The product comes with a warning that it is designed and intended for competition use only or off-highway use only and should not be installed on a vehicle driven on public roads and highways.","brand":"Ford Performance","offers":[{"title":"Default Title","offer_id":52688404742456,"sku":"M-6010-BOSS302","price":2250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687899831.jpg?v=1784889654","url":"https:\/\/store.motormia.co\/products\/boss-302-engine-block","provider":"MOTORMIA","version":"1.0","type":"link"}
