I'm doing an extensive build on another engine right now.....

I found OEM chamber volume to be between 36 and 36.5 cc. When I was finished with the "joggle removal" (term used in TRD 4AG engine manual found in TRD Bible), the chambers were 37.5cc. Once the head was cut down the chambers were 33.5 cc. 33.5cc chambers, with the Euro/Singapore pistons(10 to 1), AND a STOCK head gasket(1.2mm), provide a finished compression ratio of 10.75 to 1.
