Please help me out, everything is going wrong

[T5superduty]

Alright as some of you know I got my car back finnaly a few days ago. It does not run correctly and I would like for any help at all to try and find out what exactly is wrong. I bought the distributor and ignition from a place called total performance over in detroit. Ford racing told me to go with the guy. He had rounded up all the remaining motorcraft ignition kits for the 5.0 and I was told it would be best for my car. "before I was gunna go with a really nice MSD system but was told to do this. It has been a nightmare. The thing looked used when It came to my house, and it does not put out enough spark. We thought it might have been the fireing order but both ways were tried and that was not the problem. Also the spark plugs are black as night and I was told by someone on here it might be because of the B-303 cam. Why would this be ? Please help

(1) the ignition/distributor does not put out even as much spark as my old one in it.

(2) spark plugs are black, is it because of B cam ?
