<VV> Changing Things

[Mark Durham]

Gary, if there was that much wear in the cylinders, I would wonder about
how the bearings look. I would suggest you pull at least one rod off, at
the front of the engine where there could be less oil flow, and see what
they look like. Bearings are cheap, and in my mind its easy to pull the rod
caps and keep the cylinder/piston/ring assy from the donor engine intact to
prevent any damage and to keep the units together. Also, you are then
keeping a known piston in its cylinder and you don't have to worry about
clearances.
