Main bearing question

[grtmod3d]

I'm swaping cranks from 1 block to a different block. can I reuse the main bearings in the new block or should i replace them?

If the housing bore is the same size, you should be fine.TB

Very cheap insurance to swap them if they have any time on them at all.

[grtmod3d]

only have 2 nights on them

If they look new still and don't fall out they will be fine.
