We're showing the old tach cable that is bent at 90-degrees from improper distributor installation. This is a common problem because many GM techs put the distributor in the incorrect position since Chevy engines without shielding have the distributor closer to the intake manifold runner. Before you install the distributor, look closely at the distributor base where it sits on the intake manifold. You'll find nicks from a punch that marked where the distributor was positioned from the factory.
