Q-JET...CC vs. non-CC

I know that one is computer controlled, and one isn't. I want to know the specific differences in the two. I am looking at getting one this week and the guy doesn't how to tell the difference in the two...and neither do I for that matter. I think it is off of a '87 or '88 Camaro. Did specific model years come with the cc q-jet? I have searched online and haven't been able to get much information. Thanks.

All carb'd 3rd gen V8's, 1982-1987, came with computer controlled q-jets except some export models (Canada).

The computer controlled version has an electrical connector on the front driver side corner. It will also have an electrical connector on the top passenger side corner, but some non-computer versions also have that.

Can the cc q-jet be used on a non-cc vehicle, or no?

Yes, after you add the computer, computer controlled distributor, O2 sensor, manifold absolute pressure sensor, coolant temperature sensor, and barometric pressure sensor.

Well I am definitely not going to be doing that...lol. I think he said it was from a '87 or '88 Camaro...so it looks like a no go. I appreciate it a lot. Saved me from driving a couple of hours there and back to get it.

five7kid - I have seen you post that the Q-Jet is the best street carb ever in a few different places...and that you have no love lost on some others. Are there any other carbs that you recommend for a mostly street, but some strip, car...with a hundred or so shot of nitrous to be added at a later date.

If you don't have a carb currently, and have an intake manifold that will mount a squarebore carb, then a Holley double pumper sized appropriately for your engine and the rest of your drivetrain (mostly converter stall if auto tranny).

FWIW, the factory no longer used carbs in the 1988 model year. If this car was an '88 Camaro and had a carb, it wasn't factory.

I do not currently have a carb. I have a Professional Products Vortec intake manifold, that has the dual pattern. I was thinking of going to a squarebore intake at some point, so it may be better for me to go ahead and get a squarebore carb anyways. My car is an auto tranny, and it currently has the stock torque converter. I am going to get a B&M Holeshot 2400 converter from my Dad to use, that he has laying around though.

He said the carb was from an '85 actually.
