The aluminum block 427 Darton Sleeved LS combo is a proven performer and is quickly becoming our most popular short block combination. The 427 is a big bore (4.125\") with a stroker crank (4.000\") making it a torquey beast. The large bore size allows you to use higher flowing cylinder heads, like the LS7 Style cylinder heads. This combo has become the go to for power adder guys, no matter if it's boost or nitrous!\u003c\/div\u003e\n\u003cdiv class=\"max-w-full min-w-0 [overflow-wrap:anywhere] whitespace-pre-wrap\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003e\u003cspan style=\"font-size: 10.0pt; line-height: 115%;\" lang=\"EN\"\u003eBuild Specs:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"MsoNormal\" style=\"text-align: left;\"\u003e\u003cspan lang=\"EN\"\u003eSeasoned GM Aluminum 5.3L Gen 4 Block with Darton Sleeves\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\n\u003cspan lang=\"EN\"\u003e\u003c\/span\u003e\u003cspan lang=\"EN\"\u003eBlocks are CNC Decked, CNC Bored and CNC Torque Plate Honed\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e\n\u003cspan lang=\"EN\"\u003e\u003c\/span\u003e\u003cspan lang=\"EN\"\u003e1600hp Extreme RPM CCW Crankshaft with welded reluctor wheel\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e1600hp Rated Heavy Duty Connecting Rods\u003c\/li\u003e\n\u003cli\u003e2618 Forged Pistons (Dependent on Availability) Your choice of Flat Top or Dish\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan lang=\"EN\"\u003e\u003cspan\u003eARP Main Studs\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eACL Main \u0026amp; Rod Bearings\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan lang=\"EN\"\u003eDurabond Cam Bearings\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan lang=\"EN\"\u003eNew block plug kit and barbell\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"Boostline Performance","offers":[{"title":"Default Title","offer_id":48153327370398,"sku":"BL427SSSSBA","price":8999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0788\/6359\/7726\/files\/388-427_c9c832e5-261c-41cd-b801-c3c4601cd936.png?v=1786993187","url":"https:\/\/hughesperformanceproducts.com\/products\/427-sleeved-aluminum-ls-short-block-street-strip-series","provider":"Hughes Performance Products ","version":"1.0","type":"link"}
