'90 360 runs like crap

[PaulRR72]

I have this '90 ram 250 ext 2wheel. The 360 in it would on occasion when cold flood and blow black smoke, sputter etc. then would clear. Same engine would run real low oil pressure to the point off shutting off due to low pressure shutdown. found a strong 360 from a 79 cordoba, swapped it in (fun!) oil pressure was OK for a week then would drop off at an idle but engine still has the flooding problem, has a new pressure sender. Is this a problem in the Holley fuel injection and how do I figure out what to fix?

If your injectors are not seating (closing) properly, they may be leaking fuel into the cumbustion chamber over night. Also check and make sure your fuel return line isn't blocked.

I would have just left the motor in the Cordoba and drove that instead.

I wonder if there's tons of gas in the engine oil now?

cordoba was...shall we say... acquired? and has a smashed steering column(not by me), no keys and no papers. is now slated for the next demo derby here.
