Want to replace carb on a 1974 1/2ton with 350cu don't know any other specs. Any shops have rebuilt ones on the shelf?

if you wheel get a Quadrajet

it should be a q-jet. they are easy to rebuild but if its a holley or a carter put a Q-jet back on it.

If there are no big problems with yours rebuild it. Rebuilt carbs you guy are junk.

the only thing i look for on a core is the throttle shaft bushing before rebuiding.......otherwise rebuild it urself with some help if u need it no prob...[36]

and yes [iagree] the rebuild ones from the jobbers are junk never work right always warrantying them and such............[27]

Damn. Its never that easy. I'm trying to do this over the phone. Its for an old farm truck. Was hoping all I had to do is grab something off the shelf here and then bring it up. When I call him how is he going to describe whether its a Q-jet, Holley or Carter?

Here is a pic of a Q-Jet. If you are going to order a rebuilt carb the PN is stamped on the drivers side back corner.

O.K. Thanx for the info. We'll figure this out yet. current problem is leak below the float bowl I think and very irregular idle. Sometimes rev's sometimes stalls. Pump is fine cuz at medium to full throttle runs fine under load and all.

needle and seat and a float will fix that.

A Q-Jet leaking under the float bowl? Never heard of that. :D

Heard of guys fixing it with seal-all. And as for the throttle shaft bushings, you can buy a reamer and replacement bushings to fix it. I bought mine through Snap-on at work, but I'm sure you can find a cheaper one out there.

sorry no exsperiance with Q-jets, ive rebuilt prob about 5 Holleys and theyve all worked better than ever once i was done, and it was pretty simple
