I've seen the Speed Pro L2268 on Summit's site for the last couple years but they've only shown the .030 and .060 over sizes. And, they list the .030 version as having .300 dome and a volume of -36.30. I've been using the volume specs of -16.80 on my L2300-.030 pistons when calculating the ballpark compression ratio. So, if that's not exact, probably only a small change in the final numbers, I'd suppose.
