I think you are wrong about the conductivity of aluminum...The MSD cap for the TBI distributor is a low-budget piece of Communist Crap.

Folks jack-up about brass terminals, but aluminum actually conducts better if not covered in corrosion. Problem with aluminum is that it gets covered in corrosion.
There is no magic in distributor caps and rotors. Damn near any brand will work, at least for awhile. Delco, Delphi, Accel are all brands I've purchased recently.
I sent the MSD cap back, though. MSD isn't the company it used to be, and it hasn't been for years.
You will gain NOTHING with a "hot-rod" ignition coil if the OEM coil is in good condition.
Aluminum ranks #4, while brass ranks #7 according to what you posted.I think you are wrong about the conductivity of aluminum...
Problem with aluminum is not when it is new. It is when it corrodes, it becomes much less conductive and overheats, shortly failing. House fires from aluminum wiring should also help prove this point. When the aluminum oxidize on the termination ends over time, it creates heat, further breaking it down. I only run brass terminal caps, they offer much better longevity.I think you are wrong about the conductivity of aluminum...
Thrue.. its wierd though why they dont make them out of pure copper Aluminum ranks #4, while brass ranks #7 according to what you posted.
Copper corrodes readily. Or greenily, depending on your sense of humor.Thrue.. its wierd though why they dont make them out of pure copper
Alchemist sign for iron.
There was a time when Ford wanted the rotor tip or distributor cap contacts to be dabbed with dielectric grease. I thought it was nuts at the time. The grease looked like death once it'd gotten thousands of miles on it. This was 1980s. I think--but have not confirmed--that they were reducing the RFI of the spark-gap between rotor tip and distributor cap terminals.In order to prevent the aluminum contacts from corroding, what about covering them in dielectric grease. Would that interfere with the conductivity too much?
