Here is a good video on the Sun 504 Distributer Machines. I used one on a 289 to setup the timing curve on a Mallory distributor 45 years ago. Probably ten years ago I had a chance to buy one cheap, so I brought home. It took me a while to find the flathead distributer adapter and I bought it. I haven't used it yet. I paid as much for the flathead distributor adaptor as I did the entire 504 machine. When the distributer is working correctly all eight lights will be flashing at the same spots. If the points are bad the lights will start jumping all over the place. It lets you check to make sure each cylinder is firing exactly when it's supposed to be. Checks for worn bushings or a distributor cam. Checks the advance. I worked in a fleet with 400 vehicles for 30-years, and we didn't have a distributer machine, we did have a sun scope but no distributer machine. You don't really need one, except for checking the alignment of each cam lobe, but they are fun to play with if you have the distributer off of the engine. Mostly, it makes a nice-looking cabinet for storing my flathead distributor parts in.

This one is not a flathead but it' still good.
