Hello gentleman , new to site hoping to get some help, I have undergone the motor and trans swap on a 2000 3500, the 5.7 motor was shot and had a 92 454 motorhome donor, I thought I had read it was reasonably simple swap as far as harness to goes but doesn't appear to be , has anyone done this swap and have any helpful advice ? So far they both had 4l80 e trans and those are simple as far as tail piece swap, I haven't checked but read about exhaust changes . What's the biggest hurdle ? Thanks in advance !
