If it was running, and oil pressure was OK, then it should still be Ok, Perhaps just a fuel pump? otherwise like phoebeisis & the others, buy a GM Crate Motor, they are about $2K or Edelbroock sells they own engines, ect, . . . with a buck 87 on the motor it is time for a new something new. 200.000 miles on it, you got all the good out of it.
