If you need parts, drop a note to Lars. I think he's got a few parts carbs lying around.
I guess what I'm trying to say is the QJet is a perfectly good carb, and if you can save some bucks here you'll have it to spend on other projects.
BTW: If you switch to a Holley or Edelbrock Performer, you'll have to change the intake manifold, too.

Stock Q-Jet is 750 cfm. There's no reason to replace it - anything on a Q-Jet can be rebuilt or repaired, including anything related to the choke system. Almost all parts are available.

Keep the Q-jet,went through the same thing you are talking about two years ago ended up having it rebuilt for around hundred dollars and is probably better than new. Any other carb you get will require changes unless you use the edelbrock Q-jet repalcement so save yourself a couple of hundred and keep your old Q-jet. It has more than enough cfms to handle most mods on a 350.

Did not know holley had a direct replacement, are you sure the linkage and fuel lines do not have to be changed or modified to fit the holley?If so please let me know what model,just might be interested.

Holley's 4165 model.....650 DP. I replaced the throttle cable bracket for $9.99, but it wasn't REALLY necessary. But they actually have a (this) model that they advertise as a direct quadrajunk replacement.
I love mine....as does my 350.
