I know it's not a buick but I really need help. I bought an 84 olds delta 88. This is when GM started electronically controlling carbs, STUPID!!! Well all of the hoses were dry rotted and it acts up somewhat. Well I ripped it all off and went to a regular carb. The problem is that the holley I put on I believe is too big. Don't know what size it is only that I took it off of my diplomat when I put an edelbrock on. I know nothing about carbs but am slowly learning. Will the original electronic q-jet work just as good even though it won't be hooked to the electronics. Also the distributor has no vacume advance. It to is electronically controlled. Will the distributor still be advancing correctly or is it controled by the electronic carb. Also does spread bore mean that the secondaries are larger and square bore mean that they are equall to the primaries. I'm a fuel injected man and all the carbs I've messed with so far have been just bolt and go.
Your best bet, is to go with a non electronic Q-jet, and a conventional HEI using a 4 pin module. It shouldn't be hard to find what you need in the boneyard. If you have to pass a stringent emissions test as part of the inspection process, you'll probably have problems unless you tune it right. The electronic feedback carburetor has a TPS (Throttle Position Sensor), and a mixture control solenoid. It uses an Oxygen sensor in the exhaust as well as other sensors, that the computer interprets, to set the mixture, timing, and EGR settings. The electronic spark timing distributor doesn't use a conventional mechanical or vacuum advance. It won't work on it's own. The computer controls it, and the computer needs all the right inputs to make the right adjustments, otherwise it goes into "Limp Home" mode, and the engine will not run very well.
