LS Race Bare Engine Block (54905) by RHS®. 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. 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.
