Stan, The term trapped volume is something I thought was trapped dynamicly but I now see that this is a static number because a 327 with 12 to 1 static compression ratio would have 3.71 cubic inches (or 60.84 cc's) left in the chamber at top dead center.

I am more versed with the term chamber volume or clearence volume to describe this TDC position. I have seen trapped volume refered to dynamicly but in this case its not so you are correct that we cannot establish volumetric efficiency from this chart.
