I was browsing the profiles and noticed that many of you have the MSD listed in your upgrades. I am curious as to which springs and bushing any of you are using. I have tried all of the springs and get the best throttle response with the lightest (who would have thought), but under heavy load it rattles with anything but the heaviest installed. I am just wondering if I should start messing with bushings to lower total advance.



I have the '56 repair manual and have looked everywhere for total advance from the load-o in the specs but they do not list it (or I am not looking hard enough). If anyone has that info it might help in tuning.



Thanks in advance
