Magnum and Wiring Swap

I had some time today to check things out. The distributor cap looked okay when I put the engine in, but I figured it wouldn't be a bad idea to replace it. I found the plug wire for #7 had been touching the header. It wasn't burned through, but it wouldn't have taken much longer to be burned. The distributor end of the coil wire was burned. Chared pieces came out of the boot when I pulled it off. I cut the end off and replaced it with a new terminal and boot from an MSD kit and it runs much better now. I'm going to test drive it and see what it does. I put a new VSS in, hopefully that fixes the afterfiring that sounds like an exhaust leak.
