If you feel up to it get your self a good service manual and a rebuild kit for your car and rebuild it yourself. Its really not that hard to do as long as you pay attention to what you are doing and keep the parts all together.
If you have never messed with a computer Quadrajet before, I would have a reputable shop rebuild it for you. Being a H/O, it is probably wise not to alter it too far from stock anyways because of future value. A aftermarket carb would not offer any real advantage over the original one on an otherwise stock Olds 307. If you have an engine swap in mind, I would still stay with a Quadrajet, but get one off a engine similar in size to the one being swapped in. The Quadrajet is second only to the Carter AVS in terms of street carb design and only minimally less fuel efficient than fuel injection when properly tuned. It's a set and forget design that you don't need to mess with to keep in tune, unlike a Holley which requires constant adjustment.
If you do decide to go with an aftermarket carb, keep in mind, (and I'm assuming you probably have the 200r4 OD transmission right?) you'll also need a non computer controlled distributor, and a torque converter lock up kit.

With that said that almost makes the quadrajet rebuild the best decision...since I wouldn't want put alot into this motor then have it all go waste in a future engine swap
It would make sense, probably a little cheaper too. But ssaamm just switched as I said earlier and sound like it makes a pretty decent difference. I guess it's all in what you want to do with it. If you have an engine swap in mind for the future then I'd just leave it alone and rebuild what you got. But if you don't then do a little changing and get alittle more power out of it. Whatever your decision plenty of people are here to help. Good luck.
I maybe leaning towards the aftermarket carb route since I do have a good edelbrook carb sitting on the shelf and had planned on slapping an MSD ignition so also have on hand which I could take of while swapping distributors...will I be able to retain my dual snorkel air cleaner with the edelbrock carb? Anyone have a part # for the lock up I'll need? As this would be a good time to change the fluid and filter...
You will need a air filter spacer if you use the Edelbrock carb, and it will never fit right with the stock dual snorkel. Plus, you need a TV cable geometry correction kit and a new throttle cable bracket to give the right angle of attack for the TV cable. The Edelbrock carb plus the spacer will make you lose 1-2 inches of hood clearance. By the time you are done, you will spend at least $75 on adapter pieces to run the Edelbrock carb, plus the cost of a lock up kit for the transmission, and some added hassle in getting the A/C to work without the computer. The HO 307 cars are the only ones to run the A/C through the computer.
