Welcome To The LS Revolution

Over the past few years, LS engine technology has revolutionized the GM performance aftermarket. Gen IV engines have set a new standard for factory horsepower and torque. To meet the growing demand of today’s high performance engine builders and racing enthusiasts, engineers at RHS have recently designed an all-new LS engine block for radical street and all-out racing applications.

Going beyond the limitations of other GM LS blocks, the LS Race Block is available in both standard (9.240″) and tall (9.750″) deck height combinations and is engineered for maximum clearance around a 4.600″ stroke crankshaft. This was done by raising the camshaft centerline (.388″/9.86mm) and including priority main oiling that shifts the oil galley outboard. This unique design also minimizes windage in the rotating assembly – leading to superior engine lubrication at higher RPM.

To make it friendly for existing race applications, the block contains both factory and motor plate race mounts for Gen I, Gen II, Gen III and Gen IV engines. And for quality control assurance, RHS conducts a CT scan (similar to a medical CAT scan) on each block to ensure maximum precision and consistency. Combine that with more standard features than any block on the market and you get the new benchmark of LS power, strength and compatibility.

Custom options such as oversized cam journals and super tall decks height are also available. Call for details and lead time.
