Description

Engineers at RHS have designed a high performance aluminum engine block for GM LS applications to meet the needs of race and street performance engine builders alike. 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 computeraided design and extra surface material to allow custom machining, you get the new benchmark for LS horsepower, torque and durability.
