I am new to this forum and have used the search feature, so please not sick the search nazi's on me just yet. My question/problem is this: I have a 91 4X4 reg cab truck that is a 5 speed w/o air or any options as far as that goes. The motor blew a while back and I have found a motor out of a 97 2wd that is a low milage motor for a good (to me) price. I have not found any information that shows that this will or will not work. Most cross over information shows that it might not work, so will it work or not? I am looking for basically a direct swap, no computer and wiring swap etc, just your basic motor/block swap and putting the stock intake/exhaust over on the new motor. Any help is greatly appreciated. This is our chore truck on the farm and I am really needing it up and running ASAP. Thanks in advance.
