I'm going to pre-phase everything below with "with all due respect" because i want to come off as polite as possible... BUT...
This dead horse could not be beat any further into the ground than it has been across the fitech thread, and others.
I still take this tech call daily, and I still struggle with how/why someone would possibly sacrifice the functionality of a $1500 complete EFI system, at the expense of using a 40 year old distributor. (let alone a turbo/boost application where timing control/boost retard would be critical)
buy these...done... 100% success rate.

Ken, When someone asks "will this work with my stock distributor" And you tell them YES... But then clearly state you have a mopar performance distributor, which is a mallory, with modified guys, I don't understand what favor you're doing them? Thats not a 1972 OEM distributor. It has modified guts, a different phasser, and Mallory has been purchased by three vendors since those parts were readily avail.
"will this work with my stock mopar distributor?"
1. Fitech told you no. Why is this? because you have to take it apart, Lock it, shield the wires, figure out how to phase the rotor, and then possibly STILL fight spark jump as the terminal position is closer together on the base circle than a billet type, and it STILL probably won't work because the tach signal is "dirty"
2. You just paid $1500 on a fitech and new fuel system... Do you want it to work the first time and blow you away? or spend hours playing with a distributor that they tell you won't work, with the only tech support you're going to get is on this thread, from the handful of guys who "kinda" made a mopar distributor work, when hundreds have not.
Thats all I have to add to this one, No offense meant to anyone. The above is my opinion, and apparently fitechs also.
