Stop in for a cup of coffee

One thing I have ran into helping guys out the distrib has to have a good ground, the OEM pick up does not need one but the HEI has to have one or you will fry the modules out . Just FYI I recommend a metal dual point crush gasket to do it easily.
Makes sense, as distributor isnt intended to be grounded. The clamp isnt good enough. A ground strap would work.
