In my version of “purple shafts and pinion snubbers” mopar guy ways.... I’m still using a MSD 6AL. I just can’t make that leap to the programmable stuff. Prob has something to do with thinking about how my Racepak fought me and won most the time. Do I REALLY want to rely on stuff like that to run the car??.  LOL, I'm in the same boat! All our cars use the old style MSD 6AL boxes. I tried an MSD Digital 6 box back when they first came out in 2002 or 2003 I believe. Had misfire issues w/ 2 brand new boxes. Went back to the old 6AL and all was well. As much as I hate computers, I can't bring myself to go to one of the new programmable systems yet. I know it'd benefit my setup, but all that fancy stuff works great...until it doesn't.
