I vote exhaust leak
valves way out of adjustment is my vote.. Not to be smart, but have you checked the oil lately?
Mine sounds a bit like a diesel. I also vote for both, as I can hear the exhaust leak if I crawl under the truck while its running, and my valves probably need adjusted. However, I have also noticed that the injectors on these make quite a bit of noise. Not sure if thats a sign that they are bad or what...
mine sounds like someone poured a handful of gravel in it lately, but that is another story. it is normally loud, but it doesn't sound anything like a diesel. more like a sewing machine.

valves brotha.
adjust, it should diminish greatly.

FSM calls for valve adjust every 15K miles.
Valves for sure, also I run Lucas oil treatment in mine and it makes a world of difference.
I love the sound of my 3FE.. I would describe it as a giant typewriter. Clickty/clack. And yes my vales are adjusted. I've had three 3FE engines, and they all sounded this way.
No so much diesel, but a distinct sound.

Lately mine has a diesel-ish sound when in drive but with the brake on and not moving. Gas just a little or pull forward (or put in reverse or park) and it goes away. Seemed to only happen recently (cold weather?).
Adjust your valves it makes a world of difference.
Yeah mine sounds like that. I am doing the valves sometime this month. But thats what I said last month
Ballard Cruiser- Your sound may be an exhaust rattle. I think its usually the heat sheilds on the cats that rattle when in drive and stopped. Like at a drive through or something. Thats what mine does at least. Thought I'd throw it out there. 
I've heard this from a 3FE, but it was coming from the bottom of the engine and only noticeable at idle. Valve lash sounds (to me) like a tick tick tick but not diesel-y, worn main bearings or a bad connecting rod/wrist pin sounds like a knock knock knock, IME. Does a higher viscosity oil change the sound?
Noisey fuel injectors is my vote. Mine sounds the same and I adjusted the valves as soon as I bought it with 160k. Valves were all in spec. Didn't change the noise. Put the handle of a long screw driver to your ear and touch the other end to one of the injectors. You'll immediately hear where the noise is coming from.
