Mar 06, 2022     Piston Pin Height - (0.5 hour)       Category: Engine
I measured the piston pin/compression height using the procedure in this video ( https://youtu.be/2pEPTIX8qPE ). The scribbled out numbers are before I remembered to clean the crud off the piston top.

Dirty: (45.66 + 23.90)/2 = 34.78 mm
Clean: (45.54 + 23.56)/2 = 34.55 mm

Now I can order the proper barrel shims to set my compression ratio.
