4L80e hp rating
I was just wondering how much hp a stock 4l80e should hold? I geuss Im wondering if I should start saving my money for a build tranny. 
I was also wondering if I dont use a stall convertor does that mean its easier on my tranny?

There is a conversion for this to ft/lbs.

I looked up the conversion factors (1 Newton = .22481 lbs. force and 1 ft = .3048 meters) and got a really whacky answer. 80 N/m = 5.4818 ft/lbs Even my slow pos could break that thing. Maybe i could do it with my hand...LOL .according to that calculation. Are you sure that the 80 stands for Newton Meters? The whole thing sounds kind of wierd. 5.4818 ft/lbs of max torque that it can handle? Is my math incorrect?

If I could keep my truck running long enough to get to a dyno I could answer this question. Because I obviously have enough power to smoke the '80. Tonight makes the 3rd time I have broke mine. It lost all forward gears about 3 hours ago and had to be pulled home by a LLLLL I can't say it LLL....LLightning 
At least it was my buddy.
So, my estimate is 650 rwhp can break one.
