[Healeys] A70 Motor rebore to 100

[PG]

If your going to push the envelope, you should probably have a sonic test
done to ensure that there is enough "meat" to achieve this......you want to
have at least 180" left over so that you get good heat distribution as well
as room to bore out again if required.

The sonic test will also tell the machinist to offset the bores if necessary
to center the bores.
