yep, thanks.

The area of isosceles trapezoid is 0.2794 squared centimeters. Averageing all 4 lengthe measurements gives us 7.688 centimeters. Mulitiplying the two gives us the volume of the dome...

Awesome, go ahead and do the measures first if you don't mind. It's better for there to be two independent sets of measures out there so that others can be more comfortable that we are acurate.

I believe you are using calipers. A micrometer would have more digits. A tip on the calipers: You need to zero them. You do this by fulling closing the calipers. Then there should be a set screw...

I'd go from the top edge of the pin hole to try to get the most acuracy. Then I'd measure the diameter of the hole. With those two #'s we should be able to make acurate comparisons. The key will...

OBI how acurate of a measurement can you get with your calipers of these pistons from the pin to the top of the piston (not the dome/dish but the circle around the edge).

Also, how tall is the...

8.3 is what it would be with the na pistons. The turbo pistons would make it an unworkable 7.2.

I'm planning on having them made for 9:1. That decision hasn't been finalized yet. I'm having...
