If its an LS2 the knock sensors will be on the side of the block, if its an ls1 or 6 they will be under the intake manifold.

An ls2 should dyno more like 350-360 stock.

No auto LS2 is dynoing in the 360s, that's less than 9% drivertrain loss. Not gonna happen. And if it is it's a happy dyno that just spews out good numbers.

Truth is it's more like 15-20% loss for an auto, so between 320 and 340 is about right.
