Just got my wife an '86 K5 (Man, I love her; She's so easy to please). Now I have to get it smogged. The supposedly original carb is in a crate, but the nuber comes back to a 307, not a 350. I have the original carb for my '85. So here's the question: How reliable are the electronics in these CCC carbs? The rebuild kit includes everthing except new electrical junk- just a standard kit.
