And i think skip can build the coil for 12v to if you want that...looks better works better...win win.
I agree with Murre on this. If the secondary voltage is too high on what is essentially an ignition system designed 80 years ago, it will arc over to ground at the weakest point. I had an MSD on a flathead 25 years ago that would arc over at the coil tower on the distributor cap, while there was a recent thread on the "H.A.M.B." for a gentleman with a similar setup that was eating spark plugs. It is possible to have "too much of a good thing".
