I have a question about the MSD mechanical advance adjustments. I have been running the heavy silver springs in my 427R and am going to switch to the blue springs to see how the engine likes it. No one has mentioned the bushings. I have the black bushings in mine. Is it ok to leave those with the blue springs or is it best to use a different bushing. If I understand correctly the bushing sets the amount of advance the spring weights add, so in effect, if I set my timing all in (32/34 degrees) the bushings set the amount of initial advance. Black bushing would be 14/16 degree initial timing with 32/34 all in. Different bushings would give me less initial timing for the same all in timing. Thoughts?
