ok.....msd 5 series and Chrysler ignitions are inductive discharge.

msd 6 7 series are capacitive discharge i think this is true with the old 5c 6c 7c

if you google inductive ignition vs capacitive you will see the pros and cons of each system.go to this interesting article www.chevyhiperformance.com/...inductive...ignitions.../index.html

as far as for the for what i bought,it is msd 5300,which is the msd 5200 5 series high perf inductive.it was called the 5300 cause it was made for chryslers only with the plug.he had it listed as a 6a,he was wrong.i emailed the guy who bought the 6al,and offered him more than double what he paid,i want have and test both systems....now if we can find out they made a 7al with direct plug in that wood be cool,who has the mopar performance catalog from the early to mid 90's .....
