Default When to change timing chain?

I recently purchased a used 2003 Ford F150 4.6L V8 SOHC with 120k miles on it. I'm not sure what maintenance has been done it but it seems to run pretty smoothly.

I did all the normal maintenance to catch it up (oil/oil filter change, fuel filter, air filter, flushed/refilled radiator, checked all other fluids).

I did not see a recommended mileage/time interval to change out the timing chain in the Ford maintenance booklet or in the owner's manual. My father-in-law has a 94 F150 with over 300k miles and has never changed out the timing chain.

Is there a time/mileage when I should look into replacing the timin chain on my F150? I plan on keeping it for the long haul so it needs to last.

we dont have a timing belt, but a timing chain which are suppose to last two or three times that... so... 200,000 or 300,000 miles lets hope... hopefully the lifetime of the engine

With CLAssic Oldsmobiles/Ponitacs it around 80,000.
Is you father-in-law's 94 F-150 a 300 six? Or a 5.0/5.8 job?
About 10 years ago I was hearing with the 9th generation trucks it was aobut 90,000 miles for a timing gear change.
My suggestion is to replace the unit with a steel !

My father-in-law's F150 is a straight V6 and he has really worked it hard over the past decade. He's never replaced the timing chain on his and it has 300k+ miles on it.

.4.9 300 straight 6 is gear to gear no chain to worry about.also that engine has 7 bolt main on crankshaft.those engines are built to run forever.
