bolt hole on rear top of block

My brother took apart this ls1 in 02 and i am putting it back together. There is a bolt hole on the rear top of the block right under the intake, its between the x water line rear bots.

It's either the hole for the cam sensor or the hole for the oil pressure sender.

if it is approx. 1" in diameter that is the cam sensor. the oil pressure sending unit oil is to the right of it if your standing in front of the block.

Well if you stand looking at it from the front it would be on the right rear right in that flat spot under the intake, but behind the intake. I can still get to it even with the intake on.

Thanks for the help guys its the oil pressure sending unit the one that goes straight up. the cam sensor is right next to it but the connector 90's off.
