    How hard was it to install all of it, the ignition and distributor?

    Not hard at all, mostly the hardest part was finding a place to mount it! I have also has the 6A box covered in water and mud with no problems!

    The wiring and instructions are easy to follow.

    Mike,
    Where did you end up mounting the ignition? Got any pics of the engine bay? Had one in my last vehicle, can't wait till I've got some cash to put one in the blazer. Lound & Pround, I had a MSD OffRoad Ignition in my last truck. Big difference in easy of start up and nocticable throttle responce. Hope this helps - Jay

    Which is better 6A or the Offroad box? Why? (88 K5 stock 350 if it matters). Thanks!

    Dawson,
    I went with the Offroad ignition over the 6A. Mainly because the offroad was completely vibration and waterproof. Would have liked to went with the MSD 6AL with the soft touch rev limiter, but it wasn't waterproof. Not to say that one is better that the other, but the waterproof & vibration proof feature is what sold me. Hope this helps. - Jay

    What does the soft touch rev limiter do?

    I mounted mine against the passenger side fender. When the hood is closed, the hinge stops and almost rests on the box(it doesn't though) then I have my High Vibration coil mounted up on the firewall to the left of the engine.

    The rev limter is just that limits the RPM of your motor.
    In other words when you are Blazen thru that big mud hole and you start to Hammer it due to adrenilin and whatever else, you forget to watch your RPMs the limiter will keep you from over reving your motor.
    I too have the 6A and talked with MSD about it and the only diff is that the 6A has a sigle coat of sealent epoxy or whatever they use to cover the components. The off-road is completely submerged in this stuff. Both can handel water and mud but the off-road will litterlly run under water and the 6A may fail.......
    Good luck
