I have an '89 blazer that I am about to start working on. I have a 700R4 which I am about to get rebuilt w/ HD clutches and all. It has a NP241 right now but I am considering buying a NP203. I know the 241 is geared lower than the 203 (2.72 compared to 2.01). Which one will hold up better? I will have a basically stock 350, low gears (4.88 or 5.13, I havent decided yet), 37"ish tires, 14bff & a 44 up front. Which transfer case should I run? Thanks -Mike
