36-1 trigger wheel 318/340/360/383/440

I see, its sort of an interference fit onto the taper of the pulley, then you tack it? Thats a nice setup and a good price. You run this and some sort of pickup off your upper cam cog/distributor drive and you have sequential timing.

Correct statements. After the alternator and power steering go on, you can barely tell the trigger wheel is there. I mounted the sensor itself underneath the power steering pump with a bracket off of the oil pan rail.
