Uh, make sure you have the correct wires in the correct positions. Look at the old coil packs to verify the correct spark wire placement, as the OEM coil packs are numbered.

I built a motor once and started it, with a horrible miss/backfiring/etc. It stumped me. Thought the cams were out of alignment, tore it down to verify. Everything mechanically was sound. put it all back togather, still had the backfiring/miss. It was killing me. Swapped in a new MSD ignition, still there. Etc.

Turns out, I had two plugs reversed on the coil pack. *DOH* Such a little thing, to cause s much ruckess.

Not sure what the issue is about the "spark plug boots" as you mention on these mark viiis. But I'm startnig to read about a few problems people are having.
