Block is fine, 19 days from casting to assembly is not unusual.

Std bore with no ridge which will clean up without oversized pistons would be the best case scenario.
N355370?
IS the car around?

If it is seized because of rust, that may not hurt the value too much, will probably still need bored regardless. If it is seized because the block is cracked from freezing or something else, it could very expensive to fix, if it can be? Years ago, a buddy bought a 427 block at an auction. It looked good. After together and in the car, he started getting water in oil. It had a crack looking from underside, up in cam galley area. Maybe worth fixing today, but he junked it.

I know of a 67 L71 engine which had MUCHO damage from a thrown rod, bottom of cylinder, pan rail(s) The owner took it to high end engine builder and told him if it took 3 years and 25k  he was ok with it... well 24 months and 12k later the block was solid and square without windows.
Canadian documented 67 L71 with N89 and N14, I figure 12k to keep the original block was money well spent.
