[QUOTE="3linkedchevy, post: 7315, member: 132"] My buddy just did one on his 4wd, the mount needs to be moved back about 2", new front and rear drive shafts, and he said he had to modify the transfer case input gear, then get it retuned for the 80E. If you plan on putting a good amount of power over stock, it might be something you want to look into. But bolt ons on the stock motor the 60E should be good with a quality build. I also want to go 80E on this truck, because not sure what route I go suspension wise yet, but I want to be able to go prerun the Mexico races, and 4wd can be clutch to have sometimes. [/QUOTE]
