Why do you want to run MSD?? Most Chevy and Ford guys do this to get rid of the computer or points and be able to change the timming curve. I have run my factory ignition for five years in my race truck. I have turned it over 8 thousand several times with no problem. I bought a stand alone rev limiter off of ebay made by MSD, but never installed it.Has it been done to a 1st generation?
