So, let me pose this question. What is a good, tuneable ignition that can replace the MSD? Keep in mind, the reason I went with that is the ease of tuning. I don't have a welder to weld slots shut and then file them back open. An acquaintance that happens to need a low deck Pro-Billet distributor and I'm not attached to this one. I have an MSD box, so being compatible with that would be helpful.
