'72 402 Bb - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I recently picked up a '72 BB 402 truck with a 4 speed trans, that has seen better days. Upon inspection I revealed what appearred to be a Rochester 4 bc a top a factory 4 barrel cast iron intake manifold was actually a 2 bc. This carb was shaped exactly like a 4 bc. The secondaries were solid die cast, no machine work.
The original owner said that this truck averaged between 14-16 mpg highway, without a load.
I don't know what I'd do with such an oddity, so I wanted to see if anyone would be interested in it. I can post pic's this week or email upon interest.
