For sale is a new Holley HP kit P/N 550-606, including the TFI harness (P/N 558-305) and ACDelco knock sensor (P/N 10456288, not in pictures) with pigtail harness for the knock sensor.
This kit is complete and has never been installed or powered up. My build/setup has changed directions and as much as I was looking forward to running this, I do not need it now.
This setup would be around $2000 as is purchased from Holley.
**** SOLD *****
Please message me if interested, or via text at nineonezero-3sixsix-9four2four
