What is your idle speed?
Where is your timing set?
Does your distributor have one vacuum line or two? I think the early SC only had one, for vacuum advance.
I'm starting to feel like it is a mixture issue. The more I go over the car the more I suspect the POs mechanic was a bit lazy. I've found a few vac line "repairs" (splicing lines that had broken rather than entirely replacing) that still had large cracks.

I plugged the vac line that ran from the throttle body to the smog pump control (Diverter Valve?) because it was cracked and leaking. Ever since then it has a huge cloud of white smoke when I cold start. Makes me think that the mixture was rich to cover up for some of these vacuum leaks.

Much of the parts on the motor are original. Is it crazy to consider just dropping the motor so I can easily replace all of the vac and fuel lines?

Oh and your question about the idle, it seems a little high, hovers just above 1000 and occasionally will drop to 950.
Distributor does only have one line.
I'll have to check on the timing.
