I have two ERA Cobras, both with Shelby 427 aluminum blocks and MSD billet distributors with magnetic pick ups and centrifical advance. I find in both cars that virtually everything under the distributor cap rusts excessively in a very short two year period of time. On one occasion there was so much rust on the magnetic pick up that the engine started to missfire. When I replaced the magnetic pick up, distributor cap and rotor, which were also excessively coroded, the problem stopped. Advancemechanism, springs and shaft even rust. So as a matter of routine maintenance now every two years I replace the magnetic pick up, cap and rotor, clean and blow out the distributor and replace the rusted advance springs. Both cars are driven less then 500 miles a year. Needless to say I am really unhappy with MSD and wondered if anyone has a solution to this problem?
