So, as noted in my engine blockage thread, I borrowed a borescope from a buddy yesterday and spent a chunk of time examining Annabelle.

Pistons seem to have been made in Germany; well and good:



Shadows are rather odd.

I also found some numbers I cannot discipher, and more mysterious shadows:





This corner on the top of the piston leads me to wonder...



Those look like piano top pistons from what I have read. Isn't it dd that they would be found in a 72 3.0. I thought those appeared in the DJet CSi.

Again, the number above the starter matches my VIN; but I have a 79 head, so she has previously been modified.

I'm now rather anxious to assemble Annabelle to the point where I can check my compression.
