i dumped the msd box, I have a re-man dist. and the GM 4 pin module ( petronix version ). never thought about it being bad, I have a stock 4 pin module and different dist. I can swap in. I will give all the wires a good look over as well.
maybe I will even just run a temp. hot wire from the battery to the ignition just to rule that out.
Magnum, do you have a suggestion for a cam upgrade in the 318?
