I'm sure that someone has done this before, so I am looking for some advice. I just bought a 1986 ranger in good condition body wise. The motor is shot, the steering is locked up, and I will throw a dana 33 under it on the front side just to round it out. It currently has 33's on it. I was looking for a replacement motor. The stock one is a 2.9L. I was wondering if there is a way, or how hard would it be, to put the 4.0L under it. What else would have to be swapped out? Would the stock trans mount to this? Many "rookie" questions. Looking for any advice that people have out there. Even if that means staying stock. Thanks all.
