[SEL] Friend piston questions

[Jim and Diane]

Hi Mike,

I wonder if you could machine some off of the top of the new piston which 
depends on how much meat there is on the replacement piston.  Did you try to 
figure what the compression ratio was originally and what it would change 
to?  I am inclined to think the change would be hardly noticeable but it 
would be smart to do the arithmetic just to be sure.

How to calculate the CR might make a good school paper.
