Merlin X Aluminum
World Products’ MERLIN X cast aluminum block is compatible with all GM Gen IV components (cam location is standard) and is the best foundation for building a large displacement Big Block Hemi Chevy - with total reliability. The highly refined MERLIN X has a significant number of key technical features that set it apart from the competition. Designed specifically for the street, marine and “Super” drag class market, you won’t find a better value in big block Chevrolet technology. It is also manufactured to QS-9000 quality control standards.
Total bottom end dependability is achieved through the use of 1045 alloy steel billet splayed 4-bolt mains (much stronger than commonly used 1020 steel) with genuine ARP main studs and bolts.
