I heard some story about ignition cross-fire inside the distrib.
Something about the adjacent cylinder (on the distrib tower) being on
the intake stroke accidentally firing instead of the one under
compression. Perhaps the firing order was changed to reduce this effect?
Just a guess.

Sounds good to me,,,,,,except this has 8 coils and no distributor......hmmmm
