I didn’t have that kind of time so I tried quadrajetpower out of Texas, after a couple of long conversations with them. they built a 800 cfm that’s on a 467 Pontiac in my wife’s 69’ firebird. I wouldn’t hesitate to go with them again, they did a nice job.
Multiple responses here-

Yes, Mark is another good source for Q-Jets.

I'm going to have to say that I've never seen a 283 with a Q-Jet, though. I HAVE seen them with 4GC Rochesters.

Whether you go with Mark or Cliff, make sure to give them the number off the side of the carburetor as well as the intended application, which includes cam, trans, etc., if you buy a kit. You might try Ken at Everyday Performance as well; depending on where you live, he might be closer. I rebuild my own, though. There are many parts in a carburetor that aren't in a regular kit, like the cam that pulls the secondary metering rods out of the jets when the secondary air valve opens. Cliff's kits supplies them, but I haven't bought kits from Mark or Ken, so I can't say one way or the other, with them.
