What's wrong with engineers now days?

Have you ever priced the timing chain set up for that Explorer 4.0 SOHC? I have one of the 99 Explorers too with over 250,000 miles on it. The timing chain went out and I put an 65,000 mile motor in it instead of doing the timing chains.

Never priced it, How much? Its either going to get a OHV 4.0 or sent to the junk yard when it dies, depending how I feel.

Its been a good truck, 160,000 miles and the only issue was a wheel hub/bearing at 40,000 miles and that intake o ring,
