Atomic EFI on Slant 6

It's stock ignition as of now but I do have a MSD 6 box I might end up installing. I'll probably contack MSD next and see what they recommend. They sell a 2 barrel system as well so my guess is they'll recommend I buy it.

What I meant I guess is "what are your options" for triggering the EFI? Points? Mopar breakerless dist? Would you build a crank trigger?
