Rebuilt motor sounds broke, 1400 miles but sat for 14 months Options

[rstover]

When I got the the car back from the paint shop I was anxious to get the motor running. I have made several mistakes. First I should have pulled the motor and had car hauled to paint. Second I think I should have pulled the plugs and sprayed some lubricant into cylinders before starting it when it returned. The car was at the paint shop for 14 months.

When tried to start it it was on jack stands and the seats were not in so the clutch was not in, but I am pretty sure that it was in neutral. It is hard to describe the sound, but sorta like only 2 pistons or 3 were working. This is a LE car with number matched engine so when it did not sound right I did not try again. This was like six weeks ago and it has taken about that long to get over being really pissed at myself.

At this point I have removed the engine and removed all the tin wiring and ect. I took it to a shop close by and they were going to check compression and see if they could find out anything obvious. The compression on the rear passenger side was only 30% is what they told me. They were going to check valve clearances and retest.

I have no experience with the inside of the engine and am not sure of next step or what might have gone wrong. My first thought was maybe I broke a rod upon not preparing it correctly after setting so long.

Always thankful for ideas.
