Will this work as a leading direct fire setup?
I have 2 MSD 6AL boxes and I was wondering if I hooked both boxes up to the leading magnetic pick up, then each box to thier own coil, then each coil directly to thier own leading spark plug, would this work?

I thought there was a problem with splitting the "spark" to two coils, and that it cuts the power in half. Besides I have two boxes just sitting around. I am just wondering what I have to do to utilize them

Yes, you could wire both MSD boxes to the leading pickup and use 1 per leading coil. No worth it IMO, but you can give it a shot. You would be best off either:
- 1 MSD leading firing a dual post coil (like the 2nd gen one or a twin post MSD coil)
- 1 MSD firing 2 1st gen coil (or MSD Blaster 2 or similar) coils in parallel
You could use the 2nd MSD box on trailing, but there is no real benefit there. I would just use 1 box and sell the other (or keep as a spare).

I actually tried this set up recently, using two Summit Racing digital ignition boxes and two second generation trailing coils for leading, with the trailing still stock. Worked beautifully.

I think that I have 1 or 2 bad ones. I could send one to you for no cost. You can also remove the leading ignitor and use filed down spade terminal to connect to the pickups. Search under Jeff20B. He had done connections this way and I know that he has a picture of it on here somewhere.
Edit: Here is what Jeff did (some examples with gutted ignitors, some with the filed disconnects).

Ahhh Jeff I knew you would see this, your just the guy I was looking for.
I already bought another MSD coil and when I bought my car it already had 2 MSD Boxes in it unhooked so right now I just have 1 running the leading coil in stock setup. I want to utilize both boxes will this setup work?
So I just take the ignitor off and hook the green and purple wires into the little two prong jack on the side of the distributor? Then splice the two purple and green wires together so each box gets a signal?

It works!!!!
I havent got a chance to run it for any period of time but it starts.
It was late last night when I got done, my car is so loud and my neighbours wouldn't have been too happy about me starting my car.
Today at lunch though I will be going home to start it and let it run for a bit

Well, some of us don't have the luxury of having every J-109 from every wrecked 7 in SoCal.

:police officer approaches:
Officer: Sir, why are your socks buldging out like that?
Wacky: Officer, ummm... it is a rare medical condition called umm.. ignitoritis. It causes these strange bumps on my ankles.
Officer: Okay... but why does it look like you have a gas tank under your shirt?
Wacky: Umm... uhhh... I can explain that. It's another stange medical condition called... ummm..
