    Default best/appropriate MSD system for a ZZ4

    good morning. I have a ZZ4 engine in my truck that runs just fine. I am removing the 650 carb and adding a FAST EFI (30227-kit) and would like to add an MSD box but am not sure if I should get the 6AL or the EFi model? Also, is there anything else you would recommend (i.e. why would I want to upgrade to the VK6ALSSKIT kit?)

    Thank you.

    The 6al or the MSD EFI units will work well with the Fast Fuel System. Are you just looking for a tach signal for the MSD?
    Thank you
