-the way i did this is approximate, because i filled the chamber and cylinder up to the exhaust port roof with liquid.......without using the piston at all.

-since the piston has a raised crown, thought it would give a similar result.  the difference from edge to center was 0.038 inch.

-next time will install the cylinder over a greased piston to see just how close i was.

-also will try using a plate.

photos to follow.
