On my cummins swap I am going to machine slots in the edge of the water pump pulley to generate the necessary 58 pulses per engine RPM. I can't use the Destroked kit because I am using a 2007 harmonic balancer and the OD is too large for the tone ring. The Destroked sensor will work but it might be a little bulky and it doesn't look like they sell the sensor as a stand alone part. I talked to a supplier to my work about a prox sensor and he wanted to know if it is NO or NC and also if the sensor is a NPN or PNP? Anybody know the answers? How about the cummins or ford sensors will they work? I have looked closely at the 6.0 motor out of my truck and see no crank or cam sensors where are they located?
