World Products has taken the design and manufacturing technology used on the highly successful Motown Lite small block and applied it to the big block Chevy. The most noticeable difference between these Merlin-X blocks and the Merlin Pro Lites are the reinforcing ribs on the sides of the blocks. Not only are they attractive, but they also serve a valuable purpose in improving both overall stability and cooling. The Merlin-X blocks are 100 percent compatible with Chevy Mark IV components, and are intended for use in street and Sportsman competition. Dollar for dollar, you won't find a better value.
