Hi all, newbie here, but not to mustangs. Don't let the user name confuse you! I have a 69 automatic coupe with the 302, and I need to know what the correct carb is for this engine. The previous owner put a rebuild from pep boys on it, and though it does appear to be a 2100, it's a 1.33 venturi size. I don't have a carb tag to go by. I'm fairly sure that is for a big block, or at least a bigger small block. The car is bone stock, so I don't need more carburetion, and I'm only getting 9-10mpg with it like it is.
So can anyone tell me what the proper venturi size is, and what date or other code(s) I should be looking for (and where to look) as I hunt for a replacement? Also, if you have a properly running same powered mustang, what sort of mileage do you get? Not sure what I should actually be looking for, but I think 9-10 is not it.
