Level 10 and 20 CNC race prepped blocks give you power you can feel and the winning advantage you desire.
Level 10 CNC blocks: Over 35 blueprinting operations. Dyno proven to produce 40+HP over a standard production block. CNC stroker clearanced for 331/347 or 408/427 providing you the ultimate block for easy, do-it-yourself stroker engine assembly.
Level 20 CNC blocks: All of the quality of our Level 10 plus advanced features like our Elliptical Cylinder Chamfer (on non big bore blocks) and threaded freeze plugs for more than 40+HP over a standard production block.

D.S.S. Has designed and built a new engine block fixturing system. This fixture locates the engine block of the main and cam bore centerlines, exclusively (not the oil pan rails like most other CNC block fixtures). It is this advancement that gives us the ability to produce an extremely true engine block, aiding in the production of horsepower and longevity.
