Is a brass distributor cap really better? IS there a performance gain of any kind? I have a regular cheap cap on now....

yea buddy, brass is better. i know 1st hand that the cheesy aluminum terminal pin dist. caps are crap. i had to replace an autozone special about 2,000 miles after installing it. the bottom side of the terminals extended down too far , and they became so pitted that it was missing extremely bad. as far as not buying facory, the only caps i would even have are Borg-Warner, available at pep boys.

Does brass have lower resistance than aluminum?

I'll tell you first hand that the OEM cap sucks!!
This morning, I changed mine out with a NAPA brass cap/rotor. My 5.9 has slightly less than 20M miles on it and all of the aluminum contacts in the stock cap were very corroded as was the tip of the rotor. The corrosion was litteraly caked up on the contact surfaces.
I highly recommend this change. It has got to improve spark.

The advantage to brass over aluminum is the wear and oxidation rates. Not really the conduction when new.

I haven't checked resistance of brass vs. aluminum but aluminum is known to be a very good conductor of electricity. The problem is it does not hold up well to archs. It has a low melting point and corrodes/errodes rapidly between the cap and rotor. If you want maximum performance then you would probably use an aluminum cap and change it about as often as you change your oil. I installed brass and I may never change it again. I doubt you could measure the H.P. difference between brass and aluminum caps anyway.
