MSD or not

currently in restoration
There is your answer. Go OE.

Also... lets say you decide to go to a car show a hundred or more miles away. And since you are on FABO your car can't be a trailer queen, so you are driving it. Now you are 175 miles from home and your ignition system craps out. If it is OE you can go to just about any parts store and buy ALL the parts to replace the entire ignition system including the dist. with MSD maybe you can get some of the parts.
