Does anyone know where,how hard,and if it would be worth it to change from my 1/2 ton drivetrain to a 1 ton?(you know, 400 turbo trans with transfer and 1 ton front and rears). I have an 88 K-5 Blazer, with a 6 " lift and 35" thornbirds. I'd like to take it off road but i feel assured of braking something with the stock 1/2 ton! any help would be great! thanks!!
