i had the same issue, you have to run a "switched hot" to the MSD box, msd doesn't agree with Mopar electrical systems, i have a switch on a panel that i flip so the car will run, kind of a PITA but its worth it
I have two 727 that can't seem to find out what they are, other than one is a small block and one is a big block, code on small block is 2953733, big block is 3732534. any help would be greatly appreciated.
well, that makes up my mind, was going to go with a gen3 m/p 426 hemi in my 66 dart wagon and 65 belveder, ill stay with my first idea, stroker 400s ..512"
also, if you do have a late 727, think about putting an early front servo in, it really helps 2/3 shift as well, and use the 5.0 apply lever, well worth the 25 bones
