Engine "frozen" for no apparent reason.
I have an '87 ragtop that usually is used as a driver unless I'm going someplace I really don't want to take her (Nevada's wind/sand storms are known for their ferocity and damaging effects on paint, chrome and glass). Recently, due to unusual circumstances, the car was parked (outside) for about 75 days, safe yet not driven or started at all. I've left cars sitting for periods longer than that, in more adverse climates, and I've never had to do more than a jump or prime to get the vehicle going once the original reason for parking it was corrected.
My car, however, was completely operable, was(is) meticulously maintained and babied. When I went to bring it into the my shop for a quick once over before hitting the road, the engine would not budge!
The starter strains, and will occasionally spin without engaging the flywheel if I bump it quickly. also, I cannot (yet) turn the engine over by hand. I put less than an ounce of "Miracle Oil" in each cylinder over 48 hours ago, and still nothing. I am hoping someone out there can give me that one prognosis that can explain to me the cause and cure for this condition bvefire U start pulling the heads. THANKS in advance for any ideas you'all can give me.

I am assuming you put a ratchet on the crank bolt and tried to turn it. While that should have done the trick, I would go under the car and expose the flywheel. Use a flywheel turning tool or, if you don't have one, use a prybar to try and rotate the flywheel. This method will allow you much more leverage to try and rotate the engine. you will also be able to see if something broke off your starter and is jammed up against the bell housing and the flywheel.

Flywheel turning tool
Unless you had a blown head gasket or some other internal engine damage before you parked the car, I'd check for something external hanging things up before you tear into the motor.
Good luck!
Then I would inspect the starter and make sure the bendex is not stuck out and jammed on the flywheel.
After that you are going to have to go through anything attached to the rotating assy and see what's up.
I broke a roller off a lifter once and it jammed up the cam. I hope that's not the case, unlikely as it was parked fine, but ya never know.

I've seen situtations where the piston rings lightly fuse to the cylinder wall when there is a lot of moisture present. I don't think marvel mystery oil penetrates enough. I would use the "nut busting" type of penetrating oil and let it soak for a few hours. Then after removing accesory belt, I would get a breaker bar on the damper bolt and see if I could loosen it up.
Good luck with that one. Proceed slowly.

The clutch disk (if it's a stick????) is likely stuck to the pressure plate. Try to start with the transmission in neutral (and the clutch down to satisfy the start circuit).
My '68 Camaro was stored like yours, but inside, and I ended up having to replace the clutch. Got it home by doing a rolling jump start in 2nd gear.
I now store the old ones with a block behind the brake pedal that holds the clutch open.
Good luck
