I have a 7040246 Quadrajet, date code 0720. This is the real thing, guaranteed. NOT a restamp. Completely restored. Everyday Performance LLC rebuilt. Castings correct Dichromate finished. Steel pieces Yellow Zinc chromated. I want to give the V8Buick crowd 1st crack at it before I list it Auction Style on ebay. I am willing to consider trades of equal value. Get in touch with me at firstname.lastname@example.org or 860-218-5780 if you have an interest in this carb, and we can talk about it.
