Ok I have a dilemma. I have 2 carbs a post 76 Auto Quadrajet that came with the 403 I am building and a 1973 Olds 455 Manual Quadrajet. I will need to have either rebuilt and was wondering if the 455 version is better for performance and less restrictive than the later model. I can also get a fulling rebuilt one that also came off an Olds with Electric Choke which I plan on doing on whichever one I use anyway! What do you Carb Gurus Think?
