Re: MSD Ignition box
I have had the same MSD 6T ignition box in my low 10-high 9 second bracket car for over 30 years, with zero issues. And I used a MSD 6AL in my 85 Mustang Stocker, but have never used a 7 series box, so I can`t say if a 7AL may potentially be any better. Certainly didn`t notice any downfalls with the 6 series.
