Maybe MSD could redesign the rotor to give it some airfoil. Then it could suck fresh air in through the bottom vents and blow it out the top
. I have had a lot of problems with rusting and carbon button failures. The MSD solution of providing vent holes seems like one designed for the lab and not really for the general market. I sure hope you don't get caught in the rain, the FE tends to lead with the distributor. I used the same MSD 6al box and blaster coil with my Mallory distributor and never had any problem. I got talked into the MSD pro billet and I will be switching back when my new MSD cap fails.
