While we are on the subject... Should I rebuild my Qjet on my 85 C10 or buy a Holley 600CFM then? I have a 305 and will be putting in a 350 in the next few months here soon so whatever carb I have now will go on the 350. Any idea's? I have a friend that says he knows a guy that can rebuild mine and make it work just as good, if not, better than a Holley!
