I zoomed in on the numbers.
Sweet thanks! I wasn't sure where to lookup the numbers. Any idea what the rest of it means?

So 3.07 is gonna be best possible mileage correct? I have a stock 350/350 with edelbrock intake/carb, headers, HD radiator.

My plans for this truck is get it driving/stopping 100%. It will be a weekend driver, trips to the dump, home depot etc. With the occasional (maybe 3-4 times a year) trailer pull of another 67-72 GM truck on uhaul trailer. I'm gonna add a curt class 4 hitch and a brake controller.
