Not sure if any adapter exists, so you'd probably need to make one.
and have a very big 1 barrel i tried a 500 cfm 4 barrel and it JUST barley ran it was struggling so hard had to open the secondaries to get out in traffic and that destroyed the gas millage Now i have a 600cfm on it and if you keep you foot out of it it will get 20 miles per gallon on the highway. i never got past 15 mpg with 500 no mater what. it just would not let enough air in the engine. i was wrong about the 500 cfm carb. i thought is was a 500 when i bought it off eBay it was really a 470. THAT will not let enough air in.

with adapters you could but it would probably lack performance and efficiency.

Yes. Generally you would also want to replace the intake manifold as well, but there are adapters made for this purpose that work fairly well with some loss of efficiency.
