That's so funny!

Exactly what part of my statement is wrong, other than who posted it?

1. factory pistons, regardless of size, are all the same weight (i.e., with normal tolerance, 5 gm. or so). Which factory is that which requires re-balancing after boring?

2. as I said (perhaps in your eagerness to make a negative remark you overlooked it?): the difference between an .060" cylinder and an .080" cylinder is 1%.
Did you do the math, and get different results?

Find me an engine, even a new engine, that has cranking pressure or chamber volume on all cylinders match within 1%.
Try making a warranty claim on a new Ferrari about a 1% variation. 1% is excellent in anything below F1.

In summary: if there were no other differences, the .080" cylinder and any .060" cylinder would be closer than any 2 .060" cylinders chosen at random as to power, vacuum, static CR etc.

I'm interested to hear a rebuttal.
