Got a Box with a Boxer in it today...
For what I paid I'm a Happy Clam. It did have a compression issue but I could quickly see that the Exhaust valve on one side was not moving - Dave called it - stuck lifter. Had to carefully drill the valve cover bolts off as someone stripped out the socket heads. Compression is very good now. Bearings are very done and I have some internal clean up to do but its all very good apart from one Intake tube has a dent in it. Its an older one with the Air Bleed carb but I did confirm has the "latest" connecting Rods.
Quite a few differences between the ASP and the OS..
Cylinder fins are different
4 head bolts vs 6 on the ASP
3 bolt valve covers. Different Shape
Manifold center and carb are different mounting.
Even got a Pretty Gemini 160 Box
