FINALLY got the motor back in teh Oldsmobile over the past weekend. Motor out, motor back in...............seems simple enough right? Well now the engine doesn't shut off when I turn the ignition key off. Basically stock with the exception of a Mallory Unilite distributor and MSD 6AL box. I haven't started to trouble shoot yet, has anyone run across something like this? Sort of a bad ignition switch, how does this stuff happen?
