Cracked distributor caps are fairly common. Cracking one within a year is not.
As the cap heats and cools cracks can develop. I still have the MSD cap- it cracked real nicely right up the side.
You've had one for three years, that's great. Mine cracked quickly. I was just relaying my own personal experience as it pertained to the original question.
I cant answer that. It seems to me that on paper, Brass will wear faster than alumimum, so this might not work for you. Aluminum (for me anyhow) gets that nasty pitting and build-up on it - that stuff drives me nuts (it bugs me so I clean the terminals often).
Do you think you burn/wear away the contacts because of a hot spark, or could it be a run-out issue, and the damage is physical (rotor whacking the terminals from excessive dizzy bushing play)?
If I was having problems with alum, I'd try brass just for the sake of experimenting. That's just me.
The bolded statement is what happens to me except i don't clean it i just buy a new one lol. I was thinking it was from a "hot spark" because of the msd box and blaster 3 coil. Remember I'm new to msd ignition systems so thats why I thought this.
I will try a brass points cap/rotor, probably the accel one for $20. If i still have the problem i'll try a new dizzy and see if that makes any difference.

I get that tarnish on every aluminum terminal (cap and rotor) on all the vehicles I work on. None of them have ignition boxes either. I think it's pretty normal and most folks just leave it.
I'd also get that kit for 20 bucks and try it out. Good luck.
I will be doing a tune up and was thinking of getting a MSD cap and rotor kit. Are you guys happy with it or should I just get the cheapo brand from the part's store. I will be doing plugs and wires too. is $37 US a good price for the MSD car and rotor.
