Is this crank case rebuildable

[Turpentine2]

Guys I've been lurking here for a good while but I have an issue I'd like to post on and see what y'all think. I'm very mechanical but it's more guns and farm equipment for me. I bought a used block and crank for my 50 2 stroke Yamaha. I'd like to rebuild that block then install it in my motor. Then rebuild the one in the motor and keep it for a spare.
What happened is the top bearing on the crank went out and then spun in the housing. So I'm wondering if the crankcase can still be used with the damage the bearing did when it spun? Or if that can somehow be repaired. Or if I need to junk the block and find another one? I'm planning on running it over to Jeff Dunn in Conway for him to look at but just wondering what you guys think.

It could be..... but easyer to find better......I see no Damage to the next main web.......so bad crank/bearings?
