im a newbie here and i just turned 21 and my uncle gave me a 86 z28 305 with a cumputerized rochester carb on it. i was going to rebuild the carb. so i pulled it apart and wow it was trashed. i called the local NAPA store and they want $657 for a replacement holley carb that is computerized. I was wondering what i had to do to put a regular carb on it? thank very much Mitch Floyd.
