Well Matt at diyautotune does it all the time on all his Dizzy Conversions for the cam signal. He usually uses the stock reluctor and VR Sensor on the Mopars. My thinking is that it wont mess it up because it's not like it is hanging 4" off the shaft, it is pretty close to it like 5/8" or so. I guess I will be finding out soon. The bearings in the Distributor are a Brass Bushing type. Oil splashes up on the shaft past the teflon spacer and works its way to the bearings.
