I'm fortunate to have a heavy truck shop near that handles alot of hydraulic parts...and they have what I needed about 90 percent of the time.
This old ford is a 351 gas. I had bought pretty new year old I believe. But driving across interstate 90 for years to work took its toll.
I currently have a 6.ohh ford..been decent truck so far had fuel injection module put in recently starts great now. But the new 6.7s seem to have plenty of the HP's to pull
