i was gonna ask you if there was a shiny spot on the balancer.

if it was the balancer, youd hear it even when cold.

I assume the noise tracks with rpm right? Have you tried the loosen the injector line trick to rule out fuel knock?

I don't really hear this noise when I raise the rpms. Seems to go away when I give it some juice. It definitely isn't a piston hitting a valve, because that noise was consistent with varying rpm's.
I have taken this thing apart so many times it's ridiculous.
Don't know why it doesn't make any noise when cold tho...
To answer your question, yes I have cracked injector lines and can't really tell difference. These things are too loud

start it up cold with the solenoid advance disconnected.
or when its making the noise, jump 12V to the advance and see if it changes.

My high idle and cold advance has been disconnected for years since it doesn't work properly.
I suppose a bad balancer might make noise for the same reason you get gear rollover noise. It could slop back and forth until the engine smooths out at the higher rpm. I don't know how you would tell unless it's real bad unless you swap it out.
That would make sense as to why it's worse with the engine loaded. If you are sure it's not in the valve train the hot cold thing is still a mystery to me. I'm not sure if hot and cold would effect the balancer. It might the fan clutch though.

I will take all the belts off and see what we got. Looking underneath it when running, the balancer looks like it wobbles just a hair. dont know if that's normal or not.
Just in case you don't know it.
The balancer "pulley" is a three part pulley, hub--rubber insert--grooved pulley.
The rubber can become deteriorated or loose if some one has used the wrong puller to take it off. It really shouldn't wobble. Also if any other accessory (AC, Alt. WP ) pulley's tie up it could twist the damper pulley.

I did remove the HB with the correct tool when I swapped it onto the new engine. Thanks for the additional info. Didn't have time to take belts off but inspected the HB today. Everything looked normal with it. Something tells me this is a simple fix but need to dig into it further. Put stethoscope on oil pan area and didn't hear ticking from that area.
Do u hqve a real oil pressure guage????

I have an oil pressure tester. I also plan on hooking it back up to see if there is any fluctuation in idle psi.

Checked oil psi today. Cold is damn near 50 and hot @ idle is 18 psi on the dot.....
Well, that would seem to be enough.
Did I just read in your sig that you have an Aux electric lift pump? What's it doing for you? Could you pull the mechanical one and run the electric as a diagnostic? I would think you would be able to hear the cam lobe beating on the fuel pump arm out at the pump though with the stethoscope.

The PO installed the aux fuel pump. I put stethoscope on mechanical fuel pump (also new) and it was quiet. Got tired of fooling around with it this morning. It's in the shop & they are going to try and find out where it's coming from.
