Hi. I recently inherited a 1962 Vette and in trying to get her running one of the problems I am experiencing is determining if the Holley carburetor that is on there is the correct one. The air cleaner is super thin and when you close the hood it presses up against the hood leaving an imprint-which I am told will eventually harm the paint on the topside. In my research most Holleys were on the '64s and '65s. How do I know if I have the wrong carburetor or the wrong intake manifold? Since most carburetors I find online are not original how do I know if someone put the wrong one on to "boost performance"? I have a 327 4bbl. Someone please educate/advise me. I have the list# 1850-3, the number under the list code, 1520, which is a date code?
