I've got a carter built quadrajet that needs a rebuild before I would be able to use it. As I'm stuck using a quadrajet, I was wondering if anyone else uses one of these or if anyone has an opinion on them. Are they any worse/better or the same as the standard rochester quads?

KP says to use the older rochester type,and the carters are not as good...but may be ok for a cruiser.

It is not a thermo quad. It is actually a quadrajet, made by carter. I guess for some reason, GMC contracted Carter to build the quadrajets for a while. They appear to use the same parts as the Rochester's do. The guys at the parts store looked up the numbers, and it came off a mid seventies GMC pickup. They even had a rebuild kit in stock, but had to order the new accelerator pump for it. I'll be rebuilding it over the weekend, and try to test it out, then post back what the results are, if anyone is interested.

51 i would try to find another q-jet. GM did have carter build some q-jets. the body is cast with a different material than the rochesters. They seem to be more britle. other than the body material they are the same.

Well, I went through with the rebuild on the Carter. I wasn't too excited about it as I found I was missing a couple of other small parts I needed once I tore into it. So I figured I'd pull what I needed off the barely working one I had and try it out. Bolted it down, hit the electric fuel pump to fill the bowl, looked down and saw gas pumping so that must be a good sign. Hopped in, pumped it once or twice and it fired right up. Throttle response was as good, if not better than when I had a buddies Edelbrock on for testing. Did a few test laps around the block and it's working great. Can't wait to get to the track now this Friday to really put it through it's paces.
