Not of much help but. I was over in IN. a few weeks ago. We went past a bodyshop that had a few hot rod type cars out side. So being the nosie type I stoped and talked with the owner he showed me around the shop he had several 55 56 57 chevys older Mercs more cars than I could mention.In ONE room he had steel shelves. ON those shelves he had at least 12 409s and 348s price SORRY I"M NOT SELLING THEM. He had many intakes 3x2 2x4 4 same thing no sale. I have no idea what he is planing to do with them but he would not even talk about selling them.
