I just signed up for the site. I have 4 Pontiacs (66 GTO convertible, 67 full size wagon, 73 Firebird Formula 400, and 74 GTO 455), and the wife has a 66 Mustang. Three of my Pontiacs run Quadrajets. I bought a kit from Cliff for the 74 GTO, and have been happy with it (although I still need to do some tuning with my limited tuning skills). I intend to get parts from Cliff to do the Firebird and wagon's carburetors as well. I signed up here because I know this is the best place to get advice/information on a Quadrajet.
