Can I delete knock sensor & EGR?
I am putting in an LS1 into a 67 Chevy Nova. I have a stand alone harness with a gm ecu and am running the motor with an LS6 intake manifold. I don't have smog restrictions so can I not use the EGR? Can I also not use the knock sensors as well? I know if I don't use these I would have to have them deleted from the ecu when I get it re-flashed. Thoughts?

AIR is the air injection into the exhaust manifolds. It is only used at start-up for a minute or two. It raises the exhaust temp so the cats start working sooner. Many people remove it as a weight reduction measure. Headers can be ordered with or without the AIR ports. The pump is not mounted on the engine so you most likely don't have it.
If you are installing 67 you won't need the AIR but you should get it disabled in the computer.

Which year is your engine? Gen III engines have knock sensors in the valley cover, but Gen IV have them in the side of the block.
