Does it go away under load?

Not sure. Kinda hard to hear it under load when I have LTs

Ok well its either a spun rod bearing, valvetrain noise, or a wrist pin

Im gonna drain the oil and look for metal shavings. Hopefully there aren't any and all I have to do is change the damn bearing.

Cut open the oil filter and check for contamination.

im pretty sure Whitefox nailed it, its gotta be 1 of the 3, did you use floating wristpins or press in?

I know which one i think it is.

He said the key words "back off the motor" "rattle" and "internal"

I don't think so.... Mine has been fixed for months and well over 5000 miles and it hasn't gotten any worse. I had a 94 Mark VIII that had the same type of knock that I drove for two years and it never hurt anything (That one was several bad lifters). What he is describing is EXACTLY like my issues.
