If you don't abuse it, beat on it, drag race it or get into pulling contests with it, the stock 68RFE will do everything you need it to.
Wow that's impressive you have any major problems with the motor yet ?

The 68 with 4:10 works very well. There is nothing this set up won't go over with relative ease. I always watch my egt's and trans temp when towing and drop a gear on hills keeps egt's down along with trans temps. I tow 15k with no problems
