First of all welcome to FTF!! Now im sure you have a reason why.but be warned i did this swap in a half ton yrs ago..i blew the 3:55's and could not find a replacement used being a daily driver that had to be back on the road in a short amount of down time...so i went with the 3:08.lost way more overall, than what i gained from it.
