Knock sensor needed?
I going through both motors and when I had the blocks honed and hot tanked the one knock sensor was destroyed removing it. Are they even needed in the 500EFI motors. If so will a regular GM BBC one work instead of the Mercury Racing one.

I would keep it. The 500EFI is a speed density system and has limited information to develop it's strategies, also removing it will most likely put it into "safe mode" and pull all of the timing out I don't know if they are standard GM knock sensors, but I would not be surprised if they are.
