There are three pointer locations on SBF engines: 10 o'clock, 11 o'clock and 2 o'clock. They correspond to C-, B- & A-key positions, respectively. Your harmonic damper & pointer should be purchased with the same key. You probably have an A-key damper for early motor/front cover, but a B or C pointer, which is what are offered in billet from Ford Racing. You should also consider your water pump outlet side, BTW. The pointer is generally on the opposite side of the outlet. If you have a driver's side outlet, then your pointer is correct and you should either change dampers or tape your balancer to get the timing marks right. If the latter, find exactly TDC on #1 piston, position pointer and tape the balancer so that "0" (TDC) is at the pointer.
