Well guys, I did the hei and the car ran fine but I prefer the stock set up mainly because I don't want to butch the air cleaner and can't find a nice hei air cleaner and I want to get out and show the car...as stock...I did have radio noise from motor and noticed the condensor like thing on the side of the coil (I beleive handles radio noise suppression) had the wire missing and needs to be replaced....so what is it? a condensor or? whats it called? and will i find at autozone or ebay or where?...thanks...cliff
