Tiny:

I just finished tearing the 51 235 down to the block today. The engine is in very good shape like it had been rebuilt recently but the inside of the block had the dirtiest oil I have ever seen and felt grity like pumice hand cleaner or metal shavings and I found several balls of what felt like wax (maybe old Quaker State?). I think I will hot tank her and freshen up with a ring & Bearing Kit.

Any suggestions on where to get one?
