After pulling the head on the BGT I noticed that the block has a 3
stamped beside each cylinder and the MOWOG pistons have a 3 cast into
them.  Am I correct in assuming that this means that they are bored out
30 thousandths?  I don't have a bore micrometer to check, but will rent
one in the next day or two.

Also, the camshaft has a chunk missing on the bearing surface of the
peak of the forwardmost lobe.  How in the world would that occur?
