World Products has applied the technology of the highly-successful Motown Lite small block to the big block Chevy. Intended for street and Sportsman competition, Merlin-X blocks were designed for 100% compatibility with Chevrolet Mark IV components. Reinforcing ribs on the sides improve overall stability and facilitate cooling.
