I was looking on ebay to get new carb and a lot them are electric choke which i need but they dont have the two plugs on carburators that mine has will the performace damper for using a non computer carb? 1985 berlinetta 305 is what i have right now i guess orginal carburator? Im just look for something better on gas maybe ill just have it rebuilt is this best option? I know now it leaks gas so i been told and only get 10 miles to gallon

 

I've been going through the same tpye of problem. My computer sonsors on the carb are all messed up. I just ordered a new Carter AFB carb w/ e-choke. Those 2 plugs you have don't matter, the computer can't do anything if it's not plugged in. Just buy a non-computer-controlled carb and tune it yourself.

 

Unless what you have is totally FUBAR (and that usually at the hands of a former-owner hack), your best option for a street driver is to fix up the orginal factory carb.

 

Been there done that, doesn't work. Computer goes into limp mode, there will be no timing among other things. The computer looks for input from all things that are plugged into the system. You either have to stick with the computer and all the equip. that is part of the entire system or take it all out and put a different carb and distributor with vacum advance so you can set the timing. If you have to deal with emmissions regulations then you had better send the carb out for a total rebuild. Sorry there's no cheap or easy way around it. I learned the hard way as well as the expensive way..

 

I'm getting ready to put in a 350 w/ a 700R4 tranny originally from a Chevy truck (unknown year) into an '88 Firebird that came stock w/ a V6 (fuel injected). Do I need to change the computer from the '88 V6 to install the 350? Or does it not even matter cause its carburated. The 350 and 700R4 went from the Chevy truck, to an '85 bird, and now it's getting ready to go into my '88 bird. I don't know if the computer that was in the '85 was from the truck or not. What do I need to do?

 

The V6 computer absolutely won't work with the carb.

What computer will work depends upon the truck the engine came from. There are trucks that had computer controls like 3rd gens, and there were trucks that were only partially computer controlled.

You'll need to switch over whatever made it work in the '85 to make it work in your car.

 

I'll use the computer that made the 350 work in the '85, but is there a possibly that it might not be the correct unit and will cause it to run improperly? Or if it made it run, then it's the correct computer?
