Is it missing when you get on it? What eng, how long doing it, any new mods? I would suggest R&R ing the plugs even though they look OK they CAN be deceptive. 100 psi is too high, I'm assuming cold on startup, how long has it been that high, how much when hot at idle and at cruise. Pressure reg might be sticky/stuck. I'd put a racing filter on there just to make sure it didn't burst which 100 psi is capable of doing just that(not a for certain that it would) but for the price of one of those filters I'd want the peace of mind & if it's a BB 1st take out the reg/spring out of the pump & see what you see.

It pops under load,not all the time but pretty regularly. Just flat out runs like poo and also (at times) makes a noise like if you were to tap a hammer on the driveshaft,sort of a hollow metallic sound. Could that be the chain slapping around?

Did you change the oil? Timing chain may be toast!
Now that you mention it,it may be pinging I hear.
I havent changed the oil yet. Im very frustrated with this thing,and am wondering if I want to even put anymore work into it.Im gonna set it in storage for a few days and let my frustration settle down,then try to go back and tackle it in a fresh state of mind.

Its a 400 BB in my truck. It runs 100 psi regardless of anything,(according to the gauge in the dash)
You should confirm the dash guage reading with a good mechanical guage connected to the engine , is the oil pump new ? also check the sender , does it like someone , or have you , replaced it ?

As far as replacement goes,I havent touched it. The friend I got the truck from says he never did ANYTHING to the truck in the 3 years he owned it. He got it for a good price and maybe only drove it 2X in the entire time he owned it.
