Syringe and plate kit for calculating the compression ratio of the cylinder head

This cc measurement kit for combustion chamber volume allows to:
- verify that the 4 engine chambers (2 cylinder heads) have the same filling volume
- perform cylinder head machining / selection
The plexiglass discs, with different diameters for the main engine displacements, hold a chosen colored liquid.
The volume of liquid dispensed from the syringe gives the volume in cubic centimeters needed to calculate the compression ratio.
Suitable for VW Brazilian Split Bus from 1957 to 1975.
