I havn't posted in a while just got my 70 out. Is there supposed to be a ground wire from the firewall to block on a 70 xr7 ? Thanks Bill

I'd just put in a good one anyway - the factory ones are whimpy at best

Every one of my cars has extra ground wires on them from old to new. You should see them they are 18" 4 gauge cables I found on a mothballed, now scrapped, Coast Guard icebreaker. Go from engine to chassis.

The ground wire was changed for the 1970 model year. There is not a separate wire from the block to the chassis. The ends of the ground wire attach at the battery and the front of the block behind the alternator with an additional lug that attaches to one of the regulator mounting bolts to ground the chassis.

I thought he was talking about that 8 inch long wire off of firewall.

Which does not exist on a 1970 from the factory.

So does it hurt to run one from the rear of the engine to the firewall area?
