be happy it's not an
O-300 crank!! [

The neighbor who owns the strip where I'm opperating JBN out of right now has a messed up crank - deep groove where the thrust bearing is. Among other issues... he's looking at $50K (CAD) or more to overhaul the engine. I'm not really sure why he's even considering it - conversion to an O-360 would be not much more - relatively speaking.
