The day finally arrived for me to get down to Superior Air Parts and build my O-320. Pretty impressive facility. I'm also VERY impressed with the improvements Superior as made to their engine cases and cylinders.
Started around 9am this morning and by 5pm we had all 4 cylinders in place.

A day's work
The crank shaft we started with had a little defect on it, so they insisted on replacing it. Took a little while to locate a new one in inventory, but the replacement was perfect.
