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\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003e54903U SPECIFICATIONS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eStandard Deck Height (9.240”)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e4.120” Bore (Needs Final Finish Hone Before Assembly)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e.842” Lifter Bore\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRaised cam centerline (.388”\/9.86mm) to allow larger stroke;

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\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable border=\"0\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003e\u003cstrong\u003e54901U SPECIFICATIONS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eTall Deck Height (9.750”)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e4.120” Bore (Needs Final Finish Hone Before Assembly)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e.842” Lifter Bore\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRaised cam centerline (.388”\/9.86mm) to allow larger stroke;
