***RESOLVED*** replaced dead battery, now engine doesn't turn over.

a crank bolt on a six? Ha, good luck. I used to lay the spark plug on the exhaust manifold of an LA to watch the sparks fly. MSD makes a nice crackling spark(s). Anyone mention ballast resistor? Bypass it for a test. if you give the coil 12V and jump the starter solenoid with a screwdriver it should start, see my youtube video of me doing this with no wiring harness. spark, fuel and compression.
