Well I'm preparing my 454 to go into the K5, unfortunately I don't have a carb for it. I'm thinking of going with a Quadrajet, I want to avoid aftermarket manufacturers and EFI. I also want to avoid EGR and anything that will add more complication to the install. Any recommendations on what application to get a Q-jet from? I stopped by Auto Zone and rebuilt Q-jets, with warranty are pretty cheap, but they don't have them in stock so I can't look at them before I chose one. Here's some of the applications I have in mind. 70-76 Caddy with 500 ci early 70's Monte Carlo with 454 early 70's SS Camaro with 454 early 70's one ton dually Does anyone know a link where I can look up the specs (CFM's, electric choke, non-EGR) on the carbs that came on these cars? I'm also swapping the intake, what type of bore do I need? Is spread bore the only compatible/recommended for the Q-jet? Also, would it be a waste of time to look for a Q-jet in need of a rebuild and rebuild it myself, BTW I've never rebuilt one, so is there a good book/video to help me learn? Thanks. It's not what you buy, it's what you build!
