My opinion has always been as long as the person doing it is OK with it, that's all that matters. I like and have used the MCG distributors several times. They're better suited for a drag/street machine engine IMO. They don't work for every type of engine. In those cases, I drill a kit distributor to accept the wires. I guess I'm a little OCD because when I wire an engine, I have to wire it in the correct firing order. A lot of people think you can't tell the difference. I can. But, that's just how I do things. My method is just that, my method. Everyone has their own.
