 Looks like I got a set of used high compression pistons. Book says 6.6:1 compression, part number 224754 piston blank 224753 stamped on piston. Flat top's I'm measuring about 2-1/2 compression height. Should give over 10:1 compression with 45 crankshaft. Might be for sale I just grabbed one out of the shed to measure and it looks real nice. I'll have to check the other (3) when I go up to the farm next week.

sometimes I walk out to my shop and look around and think "Who's the idiot that owns this place?"

 Theses are OEM A-C 4.000" bore high altitude pistons. Pistons should hit the valves with the 45 crankshaft.
