What in the heck is the difference if you are transporting it or feeding your engine with it? If you get into an accident the consequences will be identical. (Hopefully nothing bad will happen of course) It bolts to the frame doesn't it?

big fuel tanks
Hi you all I was reading this thread and thought I would mention that I too am changing to the 90 gallon tank in the bed. I found at northern tool & equipment company they have 90 gallon tanks with a tool box that is diamond plate for 539.00 dollars so that is what I purchased for my 76 f250 just thought that if anyone else is looking for a tank to clear it out of the cab that this was a pretty good price they are on page 51 of there catalog

If you're going to tow with that 446, you'll be sorry if you change gears.
Your timing curve might have to be changed to keep from pinging... if you go to a higher rear (3.73/3.55) it will lug more and probably ping after you had it dialed in on a dyno...
Then, you don't have the power you have now, after fighting so hard to get it to this point.
You might have LESS traction going to a higher rear, too... all that torque, and a little wheel slip, and the wheel will spin up even faster and be harder to bring under control.

I have done a bunch of towing with 3.73s and 30-31 inch tall tires. I think they are a good compromise, and even with just a 300-6 I have hauled an old Fiberform jet boat with a 455 olds. Now that sucker was heavy but the old soldier chugged right along at the speed limit, not many hills though.
