I hope I'm posting this in the right place.
I have seen some discussion about cutting the O-290d2 case cylinder holes to accept O-320 narrow deck cylinders.
I have over some time now been gathering rebuilt stuff for my O-290D2, case, crank, lifters, cam, etc. I am just about to buy the bearings. However I just accidentally bought an O-320 A2B narrow deck which isn't much good, so I got thinking I wonder if the rebuilt crank, cam, lifters from my O-290 can be used in the O-320 case and which rods can be used with the O-320 cylinders and pistons if this is possible? It appears that the crank from the O-290D2 is very close to the O-320 crank except for the bent flange.
