Carter recommended a 400 CFM carburetor for the Chevrolet 283. The 327/340 HP Corvette used a 575 CFM Carter AFB from the factory.

How does the tune of your engine compare to the Corvette 327/340?

We ran a Carter 400 CFM for many years on our shop 300 CID 6 on an Offy manifold. Plenty of carburetor.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
