I have had really good experiences with OHV 4.0s, the wrecked truck was the third one I had with that engine, and it ran great at 257K miles. Originally I was ONLY considering the OHV and 5.0, and did not know which engine this one had before going to look at it on a whim. I had cash in hand when I first looked at it, but initially walked entirely due to it having the SOHC. After sleeping on it, and given how it ran, I went back and got it the next day. It has 217K miles, NO timing chain rattle at any RPM even when cold, and runs like new. Given the early year and high miles, I think there's no way it hasn't had updated parts installed. I have seen repaired/updated SOHCs with 300-400K on them, and given the overall condition and price, I figured it was worth the gamble.
