    Where is the cheapest place to find a rebuilt one? My 750 Q-jet (put on by the PO) runs way to rich. I'm looking for one with a manual choke.

    There is no 600 cfm q-jet. From the factory they were either 750 or 795. An 850cfm version is available from Edelbrock. No 600 though. Check Autozone for a remanufactured q-jet. Pretty good deal if I remember correctly.

    Maybe I mean 650? I'm pretty sure they made a 650 Rochester QJ for small block applications.

    nope, 750, 795, and 850. even an 850 QJet should work fine on a small block. unlike most other 4bbl carbs out there, the QJet will only feed the engine the air and fuel that it needs. yours isnt sized incorrectly, it probably just needs a tune or a rebuild.

    There is no 600 cfm Rochester Quadra Jet.
    BUT
    Rochester did make a square bore carb called a 4 Jet that was around 600-650 CFM. GM used the Rochester 4GCs till they switched to the Qudrajet(4MV) in the mid 60s. They are hard to find now. They looked kind of similar to a Carter AFB.
    Just a little Rochester trivia I thought I would throw in.:grin:
