Ok, here's the deal, I have a 59 caddy factory tripower intake, what carbs does it use? I know they're Rochester, but are they the 2GC. I have been searching for info on the net, but I'm coming up with mostly mid sixties pontiac stuff. All I know about the stock setup is that it's vacuum operated, are the carb bases different? Air horns different? These are a couple of things that are supposed to be important, at least according to the pontiac pages that I saw.
