Putting down 200+HP but keeping 4wd?

[camoit]

Resize picts to below 500. That should do the trick. Keeps band with down.

This is probably too slow for a answer, but I made that change about a year ago and the 4wd transmission is still fine. In the winter you really need the 4wd or all you do is spin-out!

You will want to use the LSD out of that , which will work up front. You'll have to shim the ring gear, but it WILL WORK!
Somebody chine in, I've seen the thread but I'm not sure if it was here or on mightyd50 web site?
Where is Jeremy he knows about it. http://www.hotrodcoffeeshop.com/forum/index.php
Kane should knows about it also! these two guy's are very sharp!
Did I leave anybody else out, if I did I'm sorry, You're sharp too, That is why you are here!

This is an edit:
You only need the 3rd member/chunk. You can use your stock ring and pinion which will need to be shimmed @ the ring gear.
of course this from my memory. Ron from Salem, Oregon also knows about this detail. Where the hell is everyone?
I'm suprised no one has chined in and called bullshit yet, that alone tells me I am correct

Go get a v6 auto transmission out of a monte swap a wideblock auto bellhousing on it and be done

Exactly what I was thinking. Go with the KM148 auto tranny.
