You have many choices and you may have to modify your throttle linkage to ensure your getting full WOT. I suggest either a quadrajet for a BBO, or an edelbrock thunder series 750ish cfm.

Does that O4B have a spreadbore carb mounting pad? Not all of them did.

It'll work fine for street driving. A bit small-ish for performance use, but it should have nice throttle response & decent fuel economy.

since your engine was originally a 2V. I would think either one would probably work fine.

You might give this a try, and also before you settle on one, check out the Quadrajets.

I've got an Edelbrock performer 750 on mine and I've never been able to get it dialed in where I'm really happy with it. I believe at some point the Q-jet may be getting rebuilt to go back on.
