    I have an eldebrock 800, but know nothing about changing metering rods, etc. However, I have been told a few times that the 800 is to much for a 350 also, but let me tell ya, i love it.

    I'm assuming you have either a 1901 or 1902 Q-Jet (I have a 1904, 795 cfm, basically the same). I recently rebuilt mine and it is fairly easy once it's apart to change out the rods and jets. The only tricky part that takes a little time to do is the installation of the primary rod holder. It can be a bear to get the rods lined up in the jets and the gasket around the holder. Pay close attention to how it comes apart, because it always comes apart easier than it goes back together and don't damage the retainer ring (the kit doesn't supply a new one). You could also do it without a kit and just remove the airhorn to access the rods and jets, but why not rebuild it if you have it that far apart, especially if the gasket disintegrates.
    Edelbrock's website (www.edelbrock.com) has a p/n listing of rebuild kits and such for its Q-Jet lineup so that you can get the correct one from your local parts supplier.
    I also have my original instructions on tuning, troubleshooting, etc. if you'd like me to fax a copy of it to you. Let me know.

    I would try the carb first. A 750 edelbrock, afb, or quad generally isn't too bad depending on the mods to the motor, compression, etc. I have had friends that have used them on a 350 no problem... perfect match, but depends on what you got.

    ARQ,

    The instructions that I have are what originally came with my carb and cover the removal of the old, installation of the new, idle mixtue tuning procedure, and basic troubleshooting of the new carb. It doesn't say anything about float level adjustment (much to my dismay), nor does the rebuild kit come with any instructions or even an exploded view!
    My advice would be to call Edelbrocks Carb Help Line @ 800-416-8628 for that adjustment spec.
    Hope that helps!

    Float level should be 1/4" on your 1901.
