Looking for a 4bbl carb for 1968 318 fury

[xxcarguy]

Hoping for some help. Would like to put a 4bbl carb on my 318. Bought a manifold.
Small bolt pattern compared to later carbs.
Pics for reference.
Would it be like a 65-66. 273 Hi po carb?

I think you need a Carter AFB size carb...they have a smaller footprint than the AVS/AVS2 size carbs

Super.
I’ll look.
Is that the same as the 273?

The current Edelbrock AFB and AVS2 carbs have the dual bolt pattern on the base plate.
