I'm still in the long process of putting a turbocharged 351 in my 95gt. I'm prbably going to have to run the old 302 to pass emissions though but the old motor had a strange timing problem. The motor was completely stock except for a large k&n filter and long tube headers. I ran the car before I started to pull it apart and my timing light was shining on the opposite side of balancer than the timing numbers were on. I doubled checked and then doubled checked again to make sure I didn't have a spark plug wire crossed but this was not the case. I rotated the distributor both ways as far as it could go but still could not get any numbers to show on the balancer cover. The motor was running real f****d during all of this and no adjustments on the distributor seemed to do it any justice. I'm wondering if it could be that little module underneath where the stock air cleaner was I think it was called the spark output module. If not I was wondering if anyone thought it could be the distributor or the timing chain that could cause this. If anyone has ever expierenced this kinda of situation before or has any idea what might be wrong I'd really appreciate some info cause I'm stumped.
