    Plug wire switched?
    Cam timing?

    One or more cylinders?
    Exhaust valve not opening will do the same thing.

    Since you already fired it up with it out 180* you most likely already experienced backfiring, this can blow out power valves on Holly's if that is what your using might check for that.

    sounds like your either 180 out, have exhaust valves not opening, or your 1 tooth off in the dist gear, and its not advanced enough.
