To go beyond the limitations of other existing LS blocks, the new RHS® LS Race Block is available in both standard deck and tall deck height configurations. Additionally, this innovative aluminum block features a raised cam centerline and outboard priority main oiling to allow rod clearance for a 4.600” stroke and to minimize windage in the crankcase. And for quality control assurance, RHS® conducts a CT scan (similar to a medical CAT scan) on each block to ensure maximum casting precision and consistency. When you combine unmatched finishing quality with added clearance for increased stroke applications, precision computer aided design and extra surface material to allow custom machining, you get the new benchmark for LS horsepower, torque and durability.\u003c\/li\u003e\n  \u003cli\u003eValvetrain Capabilities: Provisions for Gen III \u0026amp; Gen IV cam \u0026amp; knock sensors \u0026amp; valley covers, Cam tunnel will accommodate stock through oversized 60mm roller bearing cams (includes cast-in lock screw pads), .842” or .904” lifters standard with material available for oversized lifter access (accepts 1.060” bushing for keyed lifters), In the standard deck, maximum pushrod angularity = Less than 2 degrees, Includes Ampco 45 cam thrust plate and aluminum rear cover, Lifter bosses designed to clear tie bar lifter.\u003c\/li\u003e\n  \u003cli\u003e54903U-904 Specifications: Standard Deck Height (9.240), 4.120” Bore (Needs Final Finish Hone Before Assembly), 0.904” Lifter Bore, Raised cam centerline (.388”\/9.86mm) to allow larger stroke; 2 extra links in the timing chain – Timing sets available from COMP®, Machined for 55mm roller cam bearing or 60mm babbit (does not come cam with bearings).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eProduct Description - Extended\u003c\/h2\u003e\n\u003cp\u003eRHS LS Block, Standard 9.240\" Deck, .904 Lifter, 55mm Roller Cam Bearing (Machined Only) - Hone to 4.120\"\u003c\/p\u003e\n\n\u003ch2\u003eFeatures and Benefits\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eP1 MFG main stud kit standard with enough material in castings to accommodate up to a 0.5” fastener\u003c\/li\u003e\n  \u003cli\u003eRHS LS Block, Standard 9.240\" Deck, .904 Lifter, 55 Roller Cam Bearing (Machined Only)\u003c\/li\u003e\n  \u003cli\u003eGen III\/Gen IV compliant with race mounts for Gen I, Gen II, Gen III \u0026amp; Gen IV engines\u003c\/li\u003e\n  \u003cli\u003e6 head bolt design w\/ full water jacket around the cylinders (based on LS7 design)\u003c\/li\u003e\n  \u003cli\u003e2 extra links in the timing chain – Timing sets available from COMP®\u003c\/li\u003e\n  \u003cli\u003eRaised cam centerline (.388”\/9.86mm) to allow larger stroke\u003c\/li\u003e\n  \u003cli\u003eRolled threads on all threaded holes for added strength\u003c\/li\u003e\n  \u003cli\u003eChilled main bearing bulkheads for added strength\u003c\/li\u003e\n  \u003cli\u003eOptimized billet main caps \u0026amp; improved windage\u003c\/li\u003e\n  \u003cli\u003e.904” lifters standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eProduct Description - Short\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eEdelbrock RHS LS Aluminum Race Block 9.240in Standard Deck 4.120in Bore 0.904in Lifter\u003c\/li\u003e\n  \u003cli\u003eRHS Engine Block\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLabel Description\u003c\/h2\u003e\n\u003cp\u003eRHS LSBlock,Tall9.24\"Deck,.904Lifter,55RollerCamBearing MachinedOnly Hone2 4.12\"\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description - Long\u003c\/h2\u003e\n\u003cp\u003eEdelbrock® RHS® High-Performance Standard-Deck LS Engine Block\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description - Invoice\u003c\/h2\u003e\n\u003cp\u003eRHS Std-Deck LS Engine Block 904Lifters\u003c\/p\u003e\n\n\u003ch2\u003eAAIA Part Type Description\u003c\/h2\u003e\n\u003cp\u003eEngine Block\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description - Abbreviated\u003c\/h2\u003e\n\u003cp\u003eRHS\u003c\/p\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":49474641002634,"sku":"T14.1037752","price":12060.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/4599\/4122\/files\/e6fa99ddd0ec52f5169681100a9e7d4fL_0bdd643f-c9e8-4810-a04b-c59e0cc2f7f8.jpg?v=1780125454","url":"https:\/\/qjipdu-tf.myshopify.com\/products\/edelbrock-rhs-ls-aluminum-race-block-9240in-standard-deck-4120in-bore-0904in-lifter-1037752-t14","provider":"SBX Performance","version":"1.0","type":"link"}
