Ok...so did some more looking/listening around...to me it definitely sounds like it's coming from the passenger's side exhaust manifold area...In searching the interwebs, seems that exhaust leaks under load produce a very similar noise to what I seem to be hearing...I don't see/smell any obvious exhaust in the engine compartment...but the sound and symptoms seem like this is a match...I listened to the engine through the valve cover and didn't hear anything- the sound seemed to be exterior to the engine...any prime suspect sites that I need to focus on first, or any tricks to locate the leak if that's it?...since the car will only produce the sound under load at certain rpm ranges and only at normal engine operating temp, coupled that there's nothing moving when I put the truck in gear and sit on the brakes and rev to 1265 rpm and the sound is still produced, but not when I rev the engine in park/neutral...
