It's a virtual gaurentee you will NOT be able to feel or measure any difference from what you have now to a new MSD6A. I like the 6AL because it DOES have the rev limiter built in. I have been none to float a few valves. 6AL I think would look better, give you one package instead of two. But some guys "hide" the MSD box anyway, so no point in using one if your gonna "hide" it and all ready have a good ignition system anyway.
