cause it didnt need domed pistons to reach that level of compression...just a shallower dish....they were close to being flat tops but not quite if i remember correctly we had them remove 10-15cc of dish in the piston...here is the formula used to calculate the ratioit looks really complicated but its not just plug in the known numbers and it will give u what u want....

The ratio is calculated by the following formula:

, where
b = cylinder bore (diameter)
s = piston stroke length
Vc = volume of the combustion chamber (including head gasket). This is the minimum volume of the space into which the fuel and air is compressed, prior to ignition. Because of the complex shape of this space, it usually is measured directly rather than calculated.
