    Since I'm just waiting until I find the right axle now instead of saving up for it I figured I could start working on other parts of the truck. I would like to rebuild the carburetor but I know damn near nothing about it. I'm pretty sure it's a Q-jet, but how do I tell what kind it is (if it is not obvious) and what model (if there is more than one) and where do you guys think I should get a rebuild kit?
    I'm very good at taking things apart and putting them back together so I do not doubt my abillity to do this, I would just like some friendly advise.

    That's because I'm the devil.

    Your best bet for an introduction into the Q-jet would be to get the HP book by Doug Roe.
    That book will tell you all about the Q-jet and how it works.
    As far as rebuild kits go NAPA kits have always worked for me.

    If you want, check out my site, (link below) under the Q-jet tech section. Will tell you some stuff about the Q-jet, what it looks like, etc. Doesn't compare to "Rochester Carburetors" By Doug Roe, from HP Books, but it will get you started :)

    I'm collecting Q-Jet carbs for a while, then one day I'm going to buy the book and make a good one.

    I right now run a 1404 500 CFM Edelbrock squarebore (Performer series) and I'm happy with it, but I know that more performance can come from a Q-jet.

    Just did the carb on my '85. Went with the book, a kit from Napa (get the number off the carb to get the right kit) and a gallon of cleaner, also from Napa. I was amazed how much crud had accumulated in there. Noticeable improvement now, truck runs much better, haven't had a chance yet to check mpg. Since I've never done this before, I did tag and number (masking tape) all vacuum hoses and cables before, and took a few pics. Ended up replacing most of the vacuum lines where the rubber parts showed slight cracks. I know it sounds silly but I was pretty stoked/relieved when it fired right up after putting it all back together...

    Yeah, I always get a warm fuzzy feeling all over when I rebuild a carb and it works great. Its kind of like when I first started dating...
