On the 376/ 385 Direct Injection engine the dome was changed from .045” high with a volume of 4.0 cc to a .060” dome height with a volume of 4.1 cc.

I wonder how many times they had to pour to arrive at the .015” taller dome only displacing .1cc more volume.

Maybe NHRA has a portable climate controlled room maintaining a standard temperature.
