Do you have any internal engine mods done making that much hp?(rods, pistons, etc) And my thoughts on the transmission are this, I dont doubt Revmaxs abilities, I doubt the 68RFE LOL, and when I found a company that makes Allison conversions for these trucks that I can get for just 2k more than a Revmax 850 68RFE, I dont see why I'd stay with the 68, and I know everyone says you can do it with a single turbo but I like to be complicated LOL, ive always wanted something twin turboed so thats the path I'd like to stick with
