Isn't this the same as what Tifosi_boy said? I thought he said cubic centemeter displacement is used for most. Which could mean total or per cylinder.TimN88 said:The question about the ferrari naming isnt entirely correct. Alot of 12 cyl ferraris used unitary displacement. A recent example is the 456. 456cc x 12=5472cc=~5.5L Tht 365, 330, 250, 166, 400, 412, etc all were named this way.
