    Perfect for Nostalgia Drag Racing or Oval Track Spec Classes
    For competition applications where superchargers, turbos, nitrous or ultra high compression results in extreme combustion pressures, World Products offers Motown Race Blocks. The most significant difference between the race block and its standard sibling is the use of splayed billet steel 4-bolt main caps that distribute load over a larger area. Other features include reinforced main webs, bulkheads, and substantial deck & walls.SPECIFICATIONS
