Cylinder bore question?

I work for a nation wide auto parts dealer,(that will remain name less) and alot of people come in every day that seem to know a good deal about cars. I have a 1996 formula 5.7. A guy came in today and said that every 1994-1996 LT1 had a problem with a cylinder 1 overbore. I have never heard of this but i tend to be over protective of my car so I thought I would ask. If any one has heard a similar rumer or knows of some info online let me know. It would be greatly appreciated.

Never heard that and I highly doubt it.
