worth a shot at trying to compare on paper ~~~ the only number you would need is the combustion chamber volume, which might be available for both the 2.6 & 3.0 somewhere in a technical manual ~~~ already knowing the compression ratio, i would assume by changing the formula around could net the chamber volume
The ratio is calculated by the following formula:
, where
=
cylinder bore (diameter)
=
piston stroke length
=
clearance volume. It is the volume of the combustion chamber (including
head gasket). This is the minimum volume of the space at the end of the compression stroke, i.e. when the piston reaches top dead center (TDC). Because of the complex shape of this space, it is usually measured directly rather than calculated.
