Not really sure. I think it's the same compression ratio as a 149/161/173 high comp red head. This is the same chamber that the 202 XU-1 engine used (red 161HC head) and they were about 10.5:1, but from memory they used slightly higher comp pistons than s

Hi Davesmonaro68

The nominal combustion chamber sizes for Holden 6 cyl engines are 45 cc for the small chamber and 54 cc for the large chamber. AFAIK this is for Red, Blue & Black.

Hi Dave

cc = ml (mm is linear measurement, cc/ml is volume)
