My 1984 C10 has a 250 (integrated head, variable venturi 2 barrel), 3 speed saginaw and a 2.73 geared 10 bolt. Not the worst combo, but far from the best.

Best fuel economy I've seen is about 13.

5.3, 4L60E and 3.42 posi are in line to go in.

Just to keep with the thread, I'm on my second of these carbs on this truck and I just can't make them work as well as I'd like.
