I have the tools to measure that, as well as a spec sheet that came with the new pistons. Being that they are 11:1 pistons as opposed to 10:1, the diameter was increased, and I believe the height as well. I have my old pistons still and my new ones laying in the garage wrapped in foam. I will go check them once the paint on the block and heads is applied. I am almost done masking...what a tedious process.
With respect to LAN, I will not post any actual dimensions on the pistons. Only whether or not they are changed. Pics are a different story though
