The battery ground wire should be bolted to the block, there is a threaded hole near the oil pressure sender is located.
there are four grounds on our stanges, the battery ground mentioned, another smaller wire from the negative battery post to a self tapping screw between the battery and the starter solenoid on the inside fender apron, a black wire from there down to a connector that goes into a wire harness below that, one on the rear of drivers side head going to the firewall and one coming from the injector harness on the passenger side under the throttle body/fuel pump regulator area that is bolted to the back of the head.
