Well, if the fuel pressure reg is new... if fuel pressure is good (34-40psi)...
Mark suggestion is the next step....

I see many "black smoke" problems lately... and there is no "unique" solution.

some are related to "grounds" problem, short in wires, AFM, bad seal at
throttle body, air leak at intake... some when cold, some only when cold,
some only when hot....  faulty distributor are also a commun problem...

Cheers, Ben
