Installed a MSD 6AL and a 2 step in my very stock 1994 Mustang 5.0. Checked initial and total timing before the install. I now have 10 degress more initial and 10 degress more total after the install and never touched the distributor. I have always used a "dial type" timing light. After checking the MSD tech forum, I have read that MSD says not to use that type of light. They suggest a plain jane, no frills light and using an alternate power supply. If my light is the culprit, why does it work properly with a 6AL? I have owned this light for many years and have never had such a problem with it.
