It's not for a buick, but it is a quad, off of a 66 olds 425. Are there any competent carb rebuilders I can send this thing to, and maybe they can tune it for some more oomph? I know there is a guy on the board here, I think in KY, but does he only do buick carbs?
I used the search function and came up with lots of results as I know this has been asked many times before. Check out this link... http://www.v8buick.com/showthread.php?s=&threadid=22631&highlight=rebuild+quadrajet
