If you rebuild the Q-jet you have, you won’t need a new intake manifold. If you buy a new square bore carb (Holley or Edelbrock) the Edelbrock manifold at the top of the page is what you want.
It actually accepts both square bore and spread bore carbs and has clearance and bolt patterns for either one.
If you decide to rebuild the Q-jet, let me know and I’ll give you some more info.

I[/url] used to buy stuff from Summit and their catalog was worth having. Order a catalog from them and you’ll have a better idea of what’s available.
Jegs is very popular nowadays. They both have websites.

T[/url]his page has some good info about rebuilding Q-jets. He has experience with warped castings, probably common in carbs older than yours. He says he’ll pay a few bucks for used ones from the wrecking yard. This makes it possible to buy another Q-jet, rebuild it and use the car at the same time. That’s what I would do in your situation. Find the right carb, pay 5 or 10 bucks for it, and take your time rebuilding it. Re bush the throttle shaft if it’s loose, and always re-seal the 4 plugs under the fuel bowl with epoxy.
Buy the best kit you can find. It should come with a gasket that goes between the carb and manifold and it should have nylon bushings where the bolts pass through. This prevents warping the bottom of the carb.

I bought this book for my performance induction class, and the depth of detail is insane. I would recommend it if you wanna do the rebuild right.

I am totally clueless on carburetor vehicles so threads like this are very educational to me. Its a diying art it seems.

All my training and education is for fuel injected vehicles only S:(

H[/url]ere’s a page from the Cliff Ruggles book about the dreaded fuel bowl plugs on the Q-jet. On early Q-jets these always leaked when the carb needed a rebuild and mechanics (even some pros) would follow the instructions that came with the rebuild kit, ignore the plugs, and their rebuilt carb would leak and bog on acceleration.
It’s best to make a screw to fit the plug holes and seal it with epoxy. Use of taps and dies is a basic skill, even for a shade tree mechanic, and cheap taps and dies from harbor freight will hold up OK.
The 1986 Q-jet may not have leaky plugs or need throttle bushings. If you dip the parts in carb cleaner, you need to check for leaks after you dip them. I don’t check them, I just make the screws and seal them in.
