Quick 1981 Carb question

but it should run without the computer system. It'll just run rich. You also need to deal with the distributor since the timing advance is run by the computer as well.

Short answer is yes it CAN run without the computer. However, it'll run like crap without it. If your computer or any of the sensors are hosed it's sometimes easier to just go to a non-computerized system. However, if everything in the system but the carburetor is working fine then just repair/replace the carb. The system isn't that bad when it works.

if the computer is gone the transmission torque converter will not lock up.. if you want it to lock up you can get a kit from bowtie or use a switch and ground the test connection under the console near the cig. lighter

Or you could use one of these to automagically lockup the TH350-c converter...

Will we pass CA visual inspection if we go to a non comp set up? Ive got an 81 as well. I think it would be hard for them to tell the difference, but then I'm new to the vette technology.

Unless you get someone that really knows what they're looking for, all they need to see is a "check engine" light come on and then go out . As long as you pass the sniffer, you should be fine. The cat and the air injection should get you there.
