To be clear, I am not afraid of the align hone and I know the difference between it and align boring. It is another $300 that I wasn't budgeting for. Budget and reliability don't usually go together, lol.. steve25 makes a good point about checking the bearings. I haven't pulled the crank out of either short block yet. The 69 had great oil pressure, that I can state. Both blocks don't show any significant signs of corrosion. I suppose their could have been core shift when cast, but I don't think .030 over would be a concern on either block.
