from another forum Wrote:With 36.25cc chambers, you're looking at around 13.7:1 compression.
With 39.5 you're looking at around 12.5:1.

Amiright?

yes you are VERY right......

13.7 would be massive, and since I was asked to supply a cylinder head with a desired static CR of 12.5 to 1, I'll need to "open up" this heads combustion chambers from a stock volume of 36.25, to a quite large 39.5cc.

The areas of enlargement are well outlined in black marker.

I've done this procedure once before.....

the top view shows before the chamber increase, the lower view shows after. Note the gap between chambers Wink

More to come.... Hurray!
