Either the purple wire or the main lead to the starter began to smoke after I attempted starting it. I disconnected the purple thinking the connection may be bad, tried again, still smoking.

Thoughts anyone, please and thank you for the help
Cranking the engine for extended periods will send a lot of amps through the wires. The battery cable carries as much as 200 amps and the small purple wire can carry up to 10 amps. This generates a lot of heat. If your wires aren't burning the insulation off then it's normal for them to get warm under these conditions.



If you have spark and 12 volts at the distributor then you have a timing problem not a charging problem. Or you have a fuel delivery problem.

Quoted from your first post.

The HEI wasn't setup even remotely correct (which I can now fix from what I read here, thank you)
Re check your distributor to piston timing you may have the distributor installed 180* out.
