Come on, setting the timing on an MSD distributor is about as easy as it gets. You can use
any timing light that works on it and, so long as you know what the bushing is that was put in it, you can just set the timing at idle and you'll know what the all in amount is going to be (yes, you should still check it though). Then just play with the springs until you find what you like. That's easier than changing a spark plug, and way easier that setting the valves, which takes some of us all day. You don't even get your hands dirty setting the timing and it's impossible to drop anything in the wrong place and ruin your day.
