The LT4 knock module is what you want. I beleive the block sensors are identical.

Yea, the lt4 knock module is the piece that hooks into the pcm. The knock sensor is on the actual block on the passenger side. The lt4 knock module is less sensitive to false knock as opposed to the lt1 knock module.
