Try switching the distributor pick up wires. I had this same problem going from a 7AL-3 to a Digital 7. When you switch from an analog box to a digital box the pick up wires need to be switched. After you switch the wires, reset the timing.

Mine worked great in my 85 w/493, wrecked it. Put the digi 6 in my 87 while it still had the /6 in it, worked great. Put the 500 in the 87 and like you, I had a missfire above 3,500 rpm or so. Checked everything, sheilded everything and rewired everything, no help. Noticed that when it would mis that the tach was jumpy. hmmm One day out for a cruise I forgot to turn on the elec fan, flipped the switch and the tach started jumpin. hmmm turned off all of the electrics and bam, no missfire. Went to a 136amp denso alt and all is good.

Swapped my 6 al to a digital 6 and now the car breaks up around 3500rpm popping thru the carb and exhaust
I check the timing after the box swap and was advanced to 45 so I brought it back down to the 34 I normally run.
only thing I did was swap boxes
everything was fine with the 6 al
it is powered and grounded at the battery
The pick up wires for the distributor is in the same spot with nothing around it
I had the same problem with 8975 retard with the 6 al removed that and put a dial style retard in and problem went away
I Wire remote starts and stereos for a living so it's not my 1st time around wiring
Any Ideas?
Thanks
Phil
I had a similar problem with my Charger a while back. MSD sells a sheilded pick up cable. This might help. It didn't with mine. I swapped distributors and that seemed to work. I went from an MP mechanical distributor to an MSD distributor and that cured it.
When I took a closer look at the old distributor, a spacer was missing that caused the cam plate/rotor to move up and down. I got rid of the car before I could try it again.
