Proflow's adjustable timing pointers are machined from quality billet aluminium and provide up to four degrees of adjustment to help ensure accurate timing and optimum performance. They will look great with your cover and are marked off with a wide span of degrees both before and after TDC, so you can get the precise timing setting that you need.

Ford Windsor engines had 3 different factory timing mark positions 10 o'clock , 11 o'clock, 2 o'clock. To determine which one you need

10 o'clock = TDC mark is 90mm back from keyway in straight up position.  See diagram Tab C

11 o'clock =  TDC mark is 40mm back from keyway in straight up position.  See diagram Tab B
