what\'s best trans/xfer case for a 75? I am building more of a hot rod blazer than an off road one. I want to retain 4wd, but I want to maximize handling and ride quality. I am not planning a lift kit or mud tires, but I do have a TPI, 383 kit, and possibly a whipple charger in the near future Anyone have suggestions for the best transmission and transfer case? I am not farmiliar with the chevy world yet, but I'd like to find an electronic-automatic that will fit. Can anyone tell me if I would have to switch to IFS to use the transfer cases that switch from 2wd to 4wd with the electronic actuator and push button??? Has anyone switched to IFS on a 73-91 K5? lastly, are there any IRS configurations available for this platform?
