I am reassembling my top end and I have this ground wire that was present on the car and runs from one of the cam plate retaining screws at the back of the Exhaust Cam Box to the firewall on Passenger's side.
I am not sure, but I strongly suspect that this is neither original nor from the factory?
The cam boxes both ohm out to the block and the firewall/chassis, so it seems redundant. Any idea why this would be there? Has anyone else seen this? Maybe it was a solution to ground isolation of the engine/transmission by a PO? I have a heavy ground from the block to the chassis so I am tempted to eliminate it.
Thanks!
Pete
