Just to try to clear things up, this is a dull knock, NOT a ping, this is a sound similar to knocking your Hand on wood not the same but that kind of dull tone only happens once and on the tranny side I can move the drive shaft up and down just a little bit is this normal?

Little bit of a thread jack. You mention the old 302s may experience a rod knock, well my 302 has recently been a victim of this. 40k km unto the re-maned long block. The noise becomes more prominent when oils warm. 100% now it's rod, every stroke, only the one.
Although it may not be a problem is there anything that can be done about it. Like a pull and clean of the lifter?

The noise issues I was referring to on both the 5.4 an 5.0 was piston related not rod and was not a durability concern.

power brake in drive w/ hood open to see if engine is lifting up. Broken motor mount?? Sway bar links ok? u-jts shouldn't have any movement in them, but shaft may move a little in trans up & Down.

5.4ford engine timing marks
2004 5.4 engine is a interference engine , it was posted as non interfaces engine Which is wrong & misleading to those who want the right information. If turn the motor over it will cause valve damage if timing marks. Are incorrect posistion.
