ATI’s Crank Pin Drill Fixture Kit for the LS & LT (non-Dry Sump LS), along with Ford Godzilla and Hemi Super Dampers allows you to install 1 or 2 dowel pins to the crank, eliminating the damper twist on the shaft. In most applications, the crank may be drilled and the pin installed with the engine in the vehicle. This is a must for engines used in circle track racing or supercharging!
