It truly is a thing of the past. I have 213,000 miles on mine and no evidence of chain wear. Trust us, you don't need to worry about it. Timing chain problems on this engine are extremely rare.
In 4 year of frequeting this board on a daily basis, i have yet to hear of 1 single person having problems with there timing chain.
That includes me with over 100k

Also stay away from Flowmasters and knock-off Flownasters. They have crappy flow and sound like ass on the Duratec. You're better off using Magnaflow straight throughs or Dynomax Ultraflows (NOT SUPER TURBOS!!!!!)

DO NOT REPLACE THE TIMING CHAINS! It is unnecessary!
Hmm, my past dealing with about every ford has been at around 100k milage, swap out chains.
I will have to look at this further, but asside from the obvious alignment, what would suggest that the chain isn't due?
I am going off my previous experiance with V8's and V6's.
hmmm what motors have you been working on that required timing chain replacement at 100k 
and what lead you to believe they needed to be replaced or did they fail???
i have built or assisted in building several motors for mustangs old and newer and have NEVER seen a timing chain that had given out in only 100k of use...are you referring to timing belts?????
100k is nothing on a 302,hell its just getting broken in,i don't see how a set of timing chains would need to be replaced at that kind of mileage,seems ridiculous to me...

A 302 will run for a looooooong time. I've had a few of those engines myself. On at least one of them, the chains were a bit slack and close enough to the tolerance limit that I replaced them. Keep in mind they have no tensioners or adjusters for the old 302 I was working on.
The Contique engine, on the other hand, has tensioners for the OHC system that keep slack out of the picture under normal conditions. That's your difference. If the chains get a bit worn or stretched, the tensioners just take up the slack.
At 200k miles (or even earlier) you may want to change the chains & tensioner system if they show any obvious signs of extreme wear, but in a properly maintained engine, that may not be needed even at that mileage.
Must be that jumbly-wumbly thing happening again.

I had to get guides and tensioners on mine last year (2005). It had about 105K miles on it at the time.

My general rule of thumb has always been in my family, 100k, install a new time chain set with an upgraded double roller or if feeling frisky a gear drive. Something I have done as long as I recall, but I do have a bad habit of hard driving. I have not messed with anything newer than a '94 Ford, and it has always been a rule of thumb for me. My stepdad was a Ford Mechanic for a long time, and when ever he has an engine torn down far enough, he'll insect the chain. All it takes is a stretched chain and a dropped valve to ruin your day...  Thanks alot for the advice, I appreciate it.
