Cajones' to pull?
Where can I find a calculator for this to get more acurate information?
Thanks.

I pulled a 4000# car on a u-haul dolly, and the starts were a pain in the rear (pun intended) I towed with the od off for a 150 miles, once I got on the interstate I went 55mph-it seemed much easier over 30mph although...
Does anyone think I hurt anything?
The 3.08 gear is only recommended for 2,200 lbs. The car on a two-wheel car dolly from U-haul would put you just shy of 3,500 lbs. The 4.9L and C6 are more than enough power, but the 2.73 rear end is killing you.
If it were me (and this is not my recommendation, just what I would do in this situation), I would put the car on a two-wheel dolly from U-Haul and go. But I would only do this if the drive were short (less than 100 miles) and the terrain was fairly flat. I would be very easy when taking off and not floor it. I'd give myself plenty of time to stop.
That's what I would do.
Should you decide to do likewise, be careful. Too much and the gear will fail. The 2.73 is rated for about 5,000 lbs which is just enough to push the truck down the road.
If this is something you'll be doing fairly often, you need lower gears. 2.73 is a car ratio, I have no idea what Ford was thinking putting it in a truck.

The 3.27 should have been standard at least, just my opinion...

I'm just a little sceptical about it,it is starting out at 20 bux. If it does work and I get it,what else would I need to sucessfuly install it?
Thanks.

You would need an install kit/set:

Hope that helps..but if you have never done a setup like that before, I don't advise going it alone.
May be better/easier/cheaper in the long run to try and chase a complete one down at a salvage yard with the gears you want.
swapping gears is not an easy thing for a first timer, but can be done if your mechanically inclined and do your research first.
I'm with BChance...hunt down a complete axle with the gears you want and make the swap. Instead of the 3.27, look for a 3.55 as it'll give you 5,000+ lbs of tow rating. It probably won't be cheaper, but it will be a lot easier. There's lots of information available on the web that can guide you through a swap if you're so inclined.
