Now in its third iteration, World’s continually upgraded MERLIN cast iron block is the perfect foundation for any big block Chevrolet engine assembly. Made of a high density iron and manufactured to QS-9000 specifications on just two fixtures to eliminate tolerance stacking common on production lines, the MERLIN III can be bored to a maximum of 4.625” and is clearanced for a 4.375” crank. With a reinforced bottom end featuring 4-bolt splayed main caps, the MERLIN III can handle serious horsepower with complete reliability. It’s an excellent all-around value too!
