rods and pistons are out of it. Going to change crank to one that has a 24x on it. Change the cam gear to 1x 3 bolt, relocate the sensors onto the side, and move cam sensor to the front. It'll be a little but I'm thinking about some ported 243's with TBSS intake to keep it simple(r) with the sensors but also to be a little cheaper than a new set of 823's. Just an idea. But anyways, converting the ls3 to be just like a gen 3 motor and run with my current harness and ECM. Is there ANY way to use the gen 3 valley cover with knock sensors instead of throwing them on the side of the block?

no you cant, the 6.2's valley is different they have to be on the sides of the block i found this out since im doing a 416 in my zo6

if your swapping cams you can get a 3 bolt cam, 3 bolt cam gear and any gen lll front timing cover and if your deleting the VVT i was told to drill and tap the holes under the valley cover for 1/4 pipe plugs

Gotcha. That's the plan for mine. I've just been lazy and unmotivated for the goals I'm trying to tackle. I would like to at least get the shortblock cleaned up in the next month or so
