Stock 4l80e holds good amount of power already, depends on how much power, I rec. RPM stay away from Monsters transmission.

At that level stock will be fine. Get a shift kit and you will be good.

Thats okay, these trannys make out around 600hp i believe for stock.
I would invet in a good shift kit Trans go, Sunnox, are good kits, around 70-120, get a good cooler a tru cool 40k is popular and easy to install, maybe a few other extras but will be good to go. Saves money for more fun stuff!
I would look into spending money on a driveshaft. If going into a truck, the 2 piece driveshafts are good but they do NOT like high speeds, i would look up a Ujoint upgrade and high speed balancing to keep from destroying a driveshaft and more.

I have a aluminum drive shaft in mine would defiantly put a better limited slip in the rear can they actually hold that much?

A built 3in thick walled steel driveshaft is what I'd do.

The factory aluminum driveshafts in the half tons are not rated for speeds above 100mph nor are they "heavy duty".

Yes a fresh stock 4L80e will hold 500hp no problem. Some have taken them to extreme power, well into the 800-900hp range and a few have touched 1000whp. How long they last at those power level is the question, so what you are after a built transmission is not exactly required.

Then I mine as well put that rear end 14 bolt and drive shaft from the Donner 02 2500hd. Do they make 8 to 6 bolt conversions?

The rear end you can swap if you want but again not required for the power level. A new rear locker is really all you need.

Still get a built driveshaft, I wouldn't trust any stock 1 piece driveshaft from that era at high speeds.
