I've got the LS2 valley cover, so i have to run external knock sensors on my LSX engine. i've got two LS1 style sensors and the Casper's adapter harness for the cam sensor and knock sensors.
Now, my problem: From what i understand, there should be a knock sensor on each side of the motor. I can't do that with mine. My headers come too close to the driver's side of the engine where the only 2 holes a sensor would fit in are located.
On the passenger's side, there's one hole that seems to be intended for a knock sensor, and then there are the 4 holes for the A/C bracket that i will not be using. Will it be ok to run a knock sensor in one of those holes like pictured below, or do i need to do something different?
Thanks

well guys, believe it or not, the search function on this site is actually useful ![Icon Lol](https://ls1tech.com/forums/images/smilies2/icon_lol.gif)
I guess what i need to do is drill out and tap a hole on either side of the engine from the LS2 size to LS1 size and hammer down....
BUT just for kicks and giggles, would what i have pictured above work? i mean, yeah it would probably "work", but would it be ok to do that?

If you don't mind would you send me the link on this. I am building an LSX 427 for the GTO and I was wondering the same thing about the knock sensors and what else is going to throw me off when I go to install it .... Did you use the LS2 style front cover or will the ls1 cover work??? Any info would help greatly

All of your other LS1 accessories and attachments will/should bolt right up to the LSX block and drop right in. The LSX block has its own specific rear cover.

Thanks for the info. I have been watching your build and wish mine was that far along, but nothing about doing this so far has been fast and for what it cost that isn't really a bad thing lets me catch back up. I should get my motor the end of this month or beginning of the next.. Thanks again for your help....
