72 CS Carb
#2
It is a 750 CFM carb, but be aware that this is a air valve secondary carb that regulates actual airflow based on actual engine needs. Frankly, you will be much better off getting a proper rebuild on the original carb than trying to adapt an aftermarket one.

Go back and read what I wrote about how the Qjet limits airflow to only what the engine needs.
Can you bolt an 800 CFM carb onto an Olds 350? Sure. Will it run right? Well, tell us what has been done to the motor, what intake, what cam, and how you plan to use the car. Oh, and WHAT "800 CFM" carb?

It is usually better to have the original carb rebuilt, the linkage, fuel line and other hookups will match perfectly. 750 CFM is more than enough for a 350 Olds. Check out Everyday Performance for a rebuild. I've only heard good reviews about them. The URM 11 1198 is a great value, I can't believe they can reman so cheaply. I'd be curious to inspect their work.

That was my experience when I bought a reman QJet carb 10 years ago. Many trips back to the auto parts store for replacements due to sometimes obvious issues (such as a visible crack across the floor of the float bowl), then eventually for a refund, all to start over at a different vendor. I finally got a carb that worked and even had the correct jets, metering rods, hanger, and stampings. It was a win but took a while to get there.
