OK, so I've had an Msd for quite some time. All the sudden one cylinder wasn't firing like it should, so we tore it down and figured the ignition was what it had to be. We sent it to MSD and they said that's what it was. Here's my question, I've got a brand new MSD Coil, all I need is the box, but should I go back with what I had (MSD) or, should I just put a stocker back on, or should I go with a DYNA? if I go with the dyna, do I need to put all the stock back on too, or can I still use the MSD COil etc. Help me out fellas. Thanks
