2 questions. first off, i plan on getting one of those kits, there is a 400 horsepower one and a 600 horsepower one. i have a 3.73 rear end, and i plan on putting between 400 and 435 horsepower on it, if i go a little over 400 horsepower do u think it would be worth getting the 600 kit, or would the 400 do just fine second, is there any sort of manuals on rebuilding these things, as i plan on doing it myself thanks for any help nick
