Mark.
Now the compression ratio is nominally 9.7 for US engines and 10.0 for European engines, so I would expect the volume to be 57.1 cc? (Displacement = 497 cc per cylinder, so V * 9.7 == 497 + V therefore V = 497 / 8.7) Or 55.2 for Europe.

96 GL Zetec ATX, white with pinstripe, nickname " Sam Smooth "
mods so far: CTA intake with homemade heat shield, KVR drilled front rotors & carbon pads w/ 500° fluid
planned mods: exhaust (want to keep it quiet), e-ram (awaiting installation), diablo chip
involuntary mods: compression increased after head gasket failure
