I just changed the springs in my MSD mechanical advance from the heavy silver to the light silver springs. This will move the full advance up 3,000 RPM. Not sure which "advance stop bushing" I have, but if the red one, the full advance was at 5,500 and now it will drop to full advance at 2,500 RPM. Not sure what to expect.
