New at Summit Racing: World Products Merlin III Blocks for Big Block Chevy

World Products’ Merlin blocks have always been a solid foundation for a big block Chevy build. What’s more, a Merlin block is usually less expensive compared to finding a good OEM core and getting it prepped and machined.

Now World Products has made the Merlin block even better. Ideal for street performance and ET bracket racing, the Merlin III is made from high density iron and CNC-machined to QS-9000 specifications on just two fixtures. That process eliminates tolerance “stacking” common on production lines, ensuring you get a block that is as close to perfect spec as modern manufacturing allows.
