    Mine faces towards the fan also. I have clearance, but it is a little close. I know when playing with the timing, my fingers get pretty close to the fan! Original fan on mine.

    Watch those fingers!! I am missing part of one, and it was no fun healing up from the accident that caused it.

    Rich my vac. cannister is facing the power steering pump. It doesn't really matter where it faces as long as you have room to turn the distributor to set the advance you want. Mike D.
