Honest answers for your Longbed 350 Mileage?

[2bits]

OK I say "honest" because I know people like to brag at how great or at the same time complain about how terrible their mileage is. I am just lookin for honest answers for what you feel like you are getting.

Here's the criteria, it is pretty middle of the road so there should be plenty, but if you don't fit in the catagory, feel free to post just note differences (like if you dropped in a 4 speed .

•350 engine
•350 Tranny
•Note 2bbl or 4bbl, and axle ratio if known
•Note other differences


That's It!
Thanks for your help! (I am looking to pick up a longbed vs a shortbed)
