Ohhh... well that's kind of a different animal I figured you had an SBM. Unfortunately it sounds like you might have to get the oil pan off anyway, or mayyybe pull the timing cover and attempt to flush the oil pan but I don't really like that idea.
Engine is held in by a Motor plate. The motor plate would have to come out and the motor held up by an engine hoist. Biggest pain in the *** is getting the headers and torsion bars out.
