Did the Ford Cleveland Foundry make a 4 bbl intake manifold for 351C 2V motor?

No, the Ford Cleveland Foundry did not make a 4-barrel intake manifold specifically designed for a 2V (two-barrel) 351 Cleveland engine. The 2V designation itself indicates a two-barrel carburetor setup. A 4-barrel intake manifold requires a different design and porting to accommodate the larger carburetor. While aftermarket companies offered 4-barrel intakes for the 351C, Ford's factory production for that engine didn't include them for the 2V version.
