what sound do gear drive chains make on a 5.0?

[PSPstang]

i am getting a noise from my 86 5.0 i recently bought.

Kind of like a slight whineing noise when you rev it and get on it going up through the RPM's
we pulled off the belt today and its coming from the front of the motor. Narrowed it down to a possible T chain,oil pump or dist.
You can see on my car that the water pump was recently changed, so someone was in there.
The car has 105K original miles and runs awesome. I have put 400 miles on it in the past week and its getting 19MPG in the city.

Sound doesn't occur consistently at idle just when its revved, thinking someone may have stuck an aftermarket timing chain in there?

Most of the time its the PS pump, but it could be timing chain.

i dont know of any chains that make noise, just gear drives (no chain) does the timing cover gasket look new?

[PSPstang]

we had the belt off to elim all the noise from steering,water/air pump etc.
i will have to check the timing cover gasket.

My double roller timing chain isn't noisy. I would think if its an actual gear drive it would make a gear noise at idle to. Like you hear coming from old street rods with gear drives.

See if the distributor gear is worn. If the gear is worn or sharp it will whine.
