Wouldn't the knock sensor hear it and retard the timing, thereby costing you power and fuel?
Part 2: Is the knock only with the newer engines after 98?
Would a 97 5.7 be likely to have it also?

The job of the knock sensor is to protect the engine if dentonation is happening. If you get false knock it can rob you of power but should also set a check engine light if it does it too often.
A knock sensor can be found on most efi cars and trucks. My 90 K1500 has one.
