Help. LS2 knock sensor question
Does anybody have a picture of where to drill out the area on the side of the block for a 6 liter iron block to relocate the LS1 sensors as I am putting in a Gen IV block into my C5. What exact size drill is needed. I saw a video of someone instead drilling out the inside the ls1 sensor slightly so that a 3/8 bolt could fit in the sensor and therefore not have to drill out the block. Apparently he was able to modify the inside metal part on the ls1 sensor w/o breaking the metal housing. Trying to figure out which method is easier or better. Thanks.

I shaved off the threads then tapped the sensor to match the current size on the block. Also if you have headers make sure that sensor and wires clear them. Mine are really tight.
