Foolish MPG question

[shelby987]

Yes, I know its going to be low, but out of curiousity (or to confirm what I think I already know) are there any opinions on what the mileage of an 85 crew cab, running 4.10's, an SM465, and a 454 with 396 vette heads would be? Its running on 36" tires and its a 4x4 srw pickup.

Yes, I am aware of the thread asking how to get 20+mpg out of a 454.....that is not what I am asking, just trying to get a general idea of what the mpg city/highway would be.

Thanks
