Where can I find this carb? (QJet)
Okay, I have a '78 Corvette. And the stock carb is a QJet. But if you don't know about this, it's a 4 barrel carb that can compete with CFI and EFI. So, I was wondering...

Where could I go to find a "beat up" QJet carb? Something I can rebuild, polish, and get some pride out of it? I've honestly never had to go looking for a new carb. Where can I get one of these? BTW, this carb is what pre-'82 Vettes used (the Sharks - Stingrays). Maybe I can go searching out a C3 Vette in a junkyard that might have one of these carbs on it? There must be a better way.

Any ideas/suggestions?

Thanks. :D

I don`t recommend you get a carb from Carbs Unlimited, who specializes in Q-jets, I already did buisness with them. when I got it, it looked new, had new throttle shaft bushings installed, so I had bright hopes for it, I installed it, it ran great, I was happy, until I shut it off. the well plugs, which had been sealed with epoxy, leaked down faster than I ever seen any leak down, even while running I noticed they leaked down, I took the carb back off, took off the base plate, stripped the epoxy off, restaked the well plugs, added new sealant, let it cure under a heat lamp for 36 hours, reassembled, installed it, same problem, I called carbs unlimited and they told me it wasn`t possible that they leaked as the carb was tested before it left on a dyno. since I had resealed them, they refused to warrenty it. however there are other places to get Q-jets, Jet, makes performance Q-jets, they have stage 1, 2 and 3, they cost a bit more, but worth it. they have the basic replacement up to full race Q-jets. Edelbrock also makes Q-jets. Q-jets are great carbs, and there simple to rebuild, here`s a site I learned alot about them and these simple mods prove to be effective.
there`s other things to lean of Q-jets, like the hanger numbers, metering rod codes and etc, Doug Roe has a book on Q-jets which is real helpful on building them as well as performace mods. good luck silver.

Around here, the average life of a Qjet in a junkyard is measured in milliseconds. You'd think they'd be all over the place, considering how many they made. But the only ones I ever see are so f'd up nobody would want them. However, if you know somebody that works there....

Thanks for the input, guys. I'll look into that book by Doug Roe. After I read up on that, then I'll get a beat up Q-Jet and restore and rebuild and modify it.

Thanks again, guys! :D


Hey, is the book you are talking about "Rochester Carburetors"
by Doug Roe? Is this the one? I think I'm going to buy it.

Get a new one from GM Performance Parts.

Actually, I was looking to get one for real cheap and spend a lot of time cleaning it up/rebuilding it/modifying it.

pretty much any q jet can match up to the intake. if youknow of any taxis that use g.m. they will probably have a few out back somewhere. mike
