Gas mileage - whachoo get?

[MrC1]

Just wondering how everyone does on gas. I'm new to these trucks and my project truck still needs a carb rebuild, so I can't complain too much I guess.

Here's my setup: '72 C20, 402, Q-jet 4bbl, 700R4 tranny, Dana 60 with 3.54s

Average MPG so far (70/30 city/hwy mix): 10.8 MPG

Now here's the rule - no embellishing your figures. No rounding up, etc., so I don't want to see anybody running a 500 hp 454 with 4.10s averaging 24 MPG! Sorry, not gonna happen!
