Yeap ... Casting # D1ZE-B ... 66.1 cc chambers.
The "factory" pistons are "domed" ... I do not have a reference for the cc value of the dome (on the factory piston).
However, you could calculate "backwards" from 11.4 "compression ratio" using the other known info and figure it out I reckon
As far as the TRW pistong you refer to ... I don't know that either
but I bet TRW does
