how do i convert to a non computer controlled carb, like an edelbrock performer series carb. can i just leave the wires unplugged or will my car not work. i have an 82 transam.

 

uh ya thats basically all there is to it.. i mean if theres no where to hook the wire up there isn't really much you can do about that... so.... start snipin wires..

Assuming you have a computer controlled carb now, there are some details that you need to consider.

The distributor is also computer controlled. If you take away the information the CC carb is feeding the computer, it goes into limp-home mode and the distributor doesn't get proper ignition timing advance. So, you need to also replace the distributor with a mechanical/vacuum advance type.

The computer also controls the lockup of the toque converter (assuming you have an automatic transmission). Without the information from the carb and distributor, the computer will no longer perform that function. So, you need to get a conversion kit, or rig up a manual switch so you can do the lockup yourself.

If you're looking for increased performance by replacing the carb, you're barking up the wrong tree. There is an article in the tech articles section of this board that tells you how to get the most out of your q-jet. Assuming your q-jet isn't totally FUBAR, it will cost you less to get it working right than it would to convert over to non-CC.

What really holds back the standard CC carb 305's are the exhaust, air cleaner, cam, and heads (and to a lesser degree, the ignition coil and module). Fix those things, and the CC q-jet will wail all over a non-CC setup.

If you insist on continuing with this non-CC route, there's no need to cut any wires. All of the computer-involved wires can be separated from the things remaining that you need, and removed by disconnecting w/o any cutting. That isn't a bad idea, considering the distinct possibility of needing to re-establish emissions controls sometime in the future.

 

hey Five Seven Kid... I went from TBI to a performer carb... got the new intake and distributor and regulator like needed to make it work... but as you were sayin about the torque converter for auto transmissions... what is that all about... could you expand on that a bit more... and what i exactly need to do.. thx alot
