Ahh, non PI stuff. Most of the ones I've seen with super high miles were 2000+ MY's.
No experience personally with PI stuff. Did they improve oil flow, main bearings, rings, etc?
Cylinder heads, oil control (updated valve seals), new pistons, not sure if they updated timing system components. Both my parents 2000 Expedition and my former 2002 are PI engines (5.4 version), theirs has 332,000Km on it now (206,000 miles) and ours had 348,000 when we sold it, has got to be well north of 400,000 now (249,000 miles) as the guy commutes with it daily. Both have the 4R100, which behind a gasser is nary indestructible.
