The truck is running and moving under it's own power! However, there's still issues.

First, the valves need to be adjusted as it has a choppy sounding idle. The timing is set correctly, but I noticed after I reconnected the ecm wire, it would fall on it's face. With it disconnected, it ran pretty good. I'm suspecting there's an issue with the ecu not advancing the timing as I had this same issues before I pulled the old engine.

The other issue is that apparently all the transmission fluid somehow leaked out. As I was driving the truck around the parking lot, it felt like the transfer case was stuck in neutral. Foot to the floor and it's barely moving. Checked the dentent cable and it seemed good. Checked dipstick and not a drop on it.
