The direct fire setup is only on the leading (bottom) plugs right? Both fire at the same time.



The trailing plugs (top) need to be distributed, cannot fire at the same time.

I have 2 MSD 6ALs on the race car, and no problems at all. What seems to be the problem?

theres a bunch of ways you can run the 6a....



you can run 2 of em, one for leading one for trailing, thru the dizzy



you can run 1 of em, and run both coils together (msd has instructions for this), also thru the dizzy



its popular right now to run 1 msd on the leading, and run 1 coil for each plug, bypassing the distributor cap



etc etc
