LS2 Freeze plugs/block holes????? knock sens? i need to know what i have to plug up.
i did my ls2 swap i did the one large freeze plug on the side, i did the 2 smaller ones in the rear, and the one push in in the front.
i noticed last night a larger (m-16) hole on the front drivers side of the block, im thinking this is a hole for a knock sensor. (which i wont run, so i will block it)
question is, are there any more holes i need to plug up?
thanks guys.
heres a couple pics of the new setup.

I pretty sure the knock sensors go in the m10, but alot of ppl are putting them in m8 but u have to re thread them.
just the freeze plugs, i dont think u have to block anything else on the block.

If you call Scoggin Dickey they are pretty good about getting all the things you need doing the swap. The knock sensors don't go in a leakable hole they just bolt to the block nearer the back on the driver's side. The holes are smaller than you describe. I'm trying to think as I type. There is the hole in the back for the reluctor pick-up on the crank. There is a hole near that big brass screw-in plug, its kinda on a square protrusion. Accessory hole, no leak. Mine is open. There are mounting points along the block for the C6 engine mounts as well as places to mount the wiring looms and ground points. If you get stuck I can go crawl under the car... its up on jacks anyways

i put a screw driver in it, and it went way in, so i figured it had to do somthing.

Don't forget the 2 oil plugs on the front and rear of the block, very important or no oil pressure. I just put together an ls2 402. PM me your email and I will send you the diagram with all the pictures out of the service manual.
