However, I would like opinions on potential problems that could develop on such a well used motor and transmission. Also an estimate on how many miles a motor would still be effective before needing replacement.
It is a Ford V10 engine.
The motor DOES have one high mileage issue. Timing chain. It is also one of those repairs that you "might as well" replace the timing chain guides, tensioners and oil pump (replace with a HD oil pump).
My SWAG is getting this done at a Ford dealer would cost about $1,000.
The flip side is, you might drive another 100k miles with no issues !
New shocks, ball joints, tie rod ends and full brake job will cost almost $1,000.
