I got some BIG plans for the K5 but now i'm at the crossroads and can't decide where to go next. For those of you that don't know I stuffed a tbi 355 in her a couple months ago and now i need to beef up the rest drivetrain. The motor will be making approx. 330 hp and 390-400 ft lbs when the map tuning is done but will eventually be more around 400 hp and 440 ft lbs when i put some 180cc darts and a 4x4 cam in a year or so and want to know if my 10bs will hold up. I want to go 14b but they don't make a cheap selectable locker and i don't even want to screw with arbs. Heres what i'm thinkin... Get cromos and the eaton E-locker for the front 10b, swap the rear for a 14ff with a lockright and be done with it. I really want to keep the rear free on the road but i doubt a 10b will stand up to that kind of tq with 36x12.50's. Any suggestions?
