You have the toughest 4:1 combo known to man. Get stickies and be done with it. Atleast that's what I would do. Then if your not happy with that add the blower like VOLT has and put a better/smaller/more stall than stock converter in it. With your gearing that thing will come to life great.
You could in essence sell your tire/wheel combo for enough to fund the new wheels. Buy stickies with tax $$. Next year do a blower and converter if your not satisfied.
#BlewTJ had 4:1 case, 5:38's, 39" Krawlers. It had good power, just not out of the hole. It wasn't the rig for me. But all it really needed was a good converter to let it flash to more than 1200 RPM.
I had a 5.44:1 in RamRod and it sucked balls. No wheel speed. I used 3:1 98% of the time.
