I finally got the Buick!

1971 Buick GS455 Stage1
This is just an awesome story an an awesome car, like a dream come true. I like Buicks and I like A bodies.

What are your plans, since it's all numbers matching do you plan to keep it original, or do bolt on mods that can be reversed?

Also, 3 intake manifolds is awesome, plus it must be rare to have a dual carb single plane with dividers, I've never seen a single plane with full dividers.

I feel like you either clean and reinstall the factory intake or if you do the dual carb then you have to do the headers with it, although that lower center header bolt looks like a total PITA.

Awesome car, I will be watching.

The car came with 3 intakes. The original. An Edelbrock B4B, ( which is what came with the Stage2 package), and an Offy high rise, single plane, dual quad setup! View attachment 534330View attachment 534331

The original owner worked at a chrome shop in the early 70's. By 1975, a lot of the car was chromed. My plan is to get the car back in the road as he had it in 1975. Leave the chrome, run the original intake, a q-jet with the ram-air air cleaner, and the headers. ( as the exhaust system is set up for the headers and is entirely chromed!)20260921_105730.jpg20260909_081927.jpg
 
The dual quad setup is my choice. But would probably be the most challenging to dial in. Plus I don’t think I’ve ever seen a setup where the carbs aren’t oriented in the same direction. It’s a killer looking setup but not really providing any increase in power until higher rpm’s come in anyway.
 
Go aluminum intake.

I noticed that too as I haven't seen that either.

However, those are not 4 corner idle carbs, and they are mounted on an intake with divided runners. That probably means if they were both facing the same direction you would only get idle fuel control for one bank with the idle screws. I have converted them to 4 corner idle but it probably wasn't common back then.

I have to say those dual carbs would look good with those headers.
