I would think twice before tearing the computer stuff out. The computer does a good job of maintaining good gas millage during daily driving and the performance is good because when the computer senses full throttle it quits controlling the air fuel mixture and let's the quadrajet do it's thing.
As described above, if you do rip it out you'll have to get a new carb, new distributor and find some way to wire up a system to enable the torque converter to lock up. After all that it will most likely get worse gas millage and not perform any better.
I think you'd be better off cleaning up the quadrajet. You can probably get by with just removing the air horn and cleaning any evidence of old gas residue. More than likely you could gain some performance by checking the secondary throttle butterfly's and making sure they open up all the way to 90 degrees. Most quadrajets from the 80's don't open the secondaries all the way and you can easily bend the small rod that stops them so you can have full throttle.
