Replacing my Ls1 with a Thompson MS 383, its a 5.3/4.8 iron block. I there a delete kit for where the crank sensor hole is on the left rear side of the block or should i use a sensor or a freeze plug?

im confused, why do you want to delete the crank sensor? you will still need it with a tms motor

CKP sensor is on right rear of block (i.e. the "other" left).

+1 confused...

PCM and/or MSD 6LS ignition controller needs to see the CKP signal.

It really depends if you standing infront or the rear of the motor

You don't delete it LOL. you need to get a new ls2 timing cover. Also the knock sensors are relocated to the side of the block instead of valley. So new valley cover as well as knock/cam sensor harness extension is needed. Places like TSP and scoggin dickey sell the conversion kits. Or just buy the parts seperatly.

Whoops I misread your post my bad. Thought you were looking to relocate it to the front of the cover from the rear. You stated that it's NOT in the rear currently, I thought you said it was moving from rear to front my bad.

You're talking about the CMP sensor... he's talking about the CKP sensor:
