Can anyone help me decode this carb number to find the applications it is for. Carter AFB Carb #3131S E6. The box says 3131S for PLYMOUTH No. 2202 889. It is brand new and has never been bolted down to an intake. It's prob worth more to some one else than it is to me. I need a carb and intake for a 360 in a project truck that this came with. Any takers?
