If you check the recycler site car-part.com you will find you can find a bunch of 4.6L ford engines with less than 100,000 miles for around $500.
They run for over 300,000 so they are almost never overhauled. (That is $3000)
It was the Straight-6 that we think was one of Ford’s finest motors.
I left that out of the post in response to someone else. Sorry for the confusion.
