This durable iron-block casting is based primarily on GM's production LS7 block, but designed with more material in key areas - including a thicker deck and bores to support displacements of 454 cubic inches or more, and unique six-bolts-per-cylinder-head- clamping capability that enables forced-induction and nitrous combinations of greater than 2,000 horsepower. Because the LSX Bowtie block is based on production LS blocks, all of the LS-Series Gen IV cylinder heads, crankshafts, oil pans, camshafts, and accessories bolt right up to it. There is also a tall-deck version for building even larger engines. Chevrolet Performance delivers the LSX Bowtie Block semi-finished, allowing you to finish it to your needs. Whether you're building a \"tame\" 500-horse street engine for your hot rod or a 1,700 horsepower turbo engine for an Outlaw drag racer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures: \u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLSX Bowtie Block specs and features include:\u003c\/li\u003e\n\u003cli\u003eCNC-machined cast iron block\u003c\/li\u003e\n\u003cli\u003eTrue priority main oiling\u003c\/li\u003e\n\u003cli\u003e6-head bolts per cylinder\u003c\/li\u003e\n\u003cli\u003eStandard 4.400\" bore spacing\u003c\/li\u003e\n\u003cli\u003eExtra-thick siamese cylinder bores\u003c\/li\u003e\n\u003cli\u003eSemi-finished, machined thicker decks\u003c\/li\u003e\n\u003cli\u003eLS7-style, 6-bolt dowel-located billet main bearing caps\u003c\/li\u003e\n\u003cli\u003eWet-sump and dry-sump oiling capability\u003c\/li\u003e\n\u003cli\u003eProduction- style deep-skirt head bolt holes\u003c\/li\u003e\n\u003cli\u003eProduction bolt hole and thread sizes\u003c\/li\u003e\n\u003cli\u003eMaintains production exterior accessory mounting provisions\u003c\/li\u003e\n\u003cli\u003eFront motor plate mounting holes added\u003c\/li\u003e\n\u003cli\u003eAdditional material cast around cam bearings for greater strength\u003c\/li\u003e\n\u003cli\u003e8mm exterior\/interior fifth- and sixth-head bolt holes\u003c\/li\u003e\n\u003cli\u003eStandard 0.842\" lifter bores\u003c\/li\u003e\n\u003cli\u003eAccommodates all LS oil pumps and oil pans\u003c\/li\u003e\n\u003cli\u003eExternal oil pump feed (rear of block)\u003c\/li\u003e\n\u003cli\u003eMain web bay-to-bay breathing holes to support greater horsepower\u003c\/li\u003e\n\u003cli\u003eIncludes unique cam retainer, rear cover and lifter retainers\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFor the advanced LSX competition engine builder, you will fully enjoy the following features of the new LSX Bowtie Block:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFront oil feed holes can be plugged\/restricted for mechanical flat tappet or mechanical roller lifter applications\u003c\/li\u003e\n\u003cli\u003eCan be machined safely to 9.200\" deck height\u003c\/li\u003e\n\u003cli\u003eMaximum 4.200\" bore at .200\" minimum wall thickness (naturally aspirated applications)\u003c\/li\u003e\n\u003cli\u003eHead bolt holes can be machined for 1\/2\" studs\u003c\/li\u003e\n\u003cli\u003eCam bores can be machined to accept 60mm roller bearings\u003c\/li\u003e\n\u003cli\u003eCan be machined for larger diameter lifters and\/or 1.060\" bronze bushings\u003c\/li\u003e\n\u003cli\u003eFront oil feed lines can be plugged and external oil pump and\/or aftermarket dry sump systems can be used via oil pump feed at rear of block may be required with certain large stroke\/aluminum rod combinations\u003c\/li\u003e\n\u003cli\u003eBelt cam drive systems can be accommodated some machining will be required\u003c\/li\u003e\n\u003cli\u003eFront motor plate can be used for racing chassis applications (sprint car, drag racing, truck pulling, etc.).\u003c\/li\u003e\n\u003cli\u003eThreaded water plugs can be used for external heaters or coolers\u003c\/li\u003e\n\u003cli\u003eExtra stock for main bearing align-honed\u003c\/li\u003e\n\u003cli\u003e400 mPa Tensile strength iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e","brand":"GM Performance","offers":[{"title":"Default Title","offer_id":44875589550391,"sku":"GM19260093","price":6187.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/83214.jpg?v=1780370764","url":"https:\/\/enginemaster.com.au\/products\/gm-performance-gm19260093-chevrolet-performance-lsx-bowtie-block-4-200-max-bore-4-250-max-stroke-9-200-deck","provider":"Engine Master","version":"1.0","type":"link"}
