0 PSI on the compression test, excellent compression on #7... 030" valve clearance would allow some compression to be built. If this is indeed correct, my guess would be the top of the piston broke and is staying at the top of the stroke while the connecting rod and remaining part of the piston and pin boss is reciprocating in the cylinder bore.

Edit: One other thought, slim... but possible. Broken crankshaft at rear of engine causing #8 not to reciprocate. Either problem, if you could get a small flexible scope and go through the spark plug hole and rotate the engine it would be easy enough to verify.

Re-Edit: the car wouldn't move if the crank were broken. Scratch that brainless thought.
