What will my compression ratio be? My 408 previously had l92 heads with a standard 69cc chamber.
Can you tell me what my compression will be with my 317s. The chamber is 71.06 from what I can tell.
Thanks I will try to find my own calculations but wanted to ask the experts.

If my calculations are correct I will be loosing around .04:1 in compression.
Seems to not be right but what I did was found the cylinder volume got what % 2 cc would be and used that % to approximate the loss of compression.
I seem to be way off so if someone could confirm my numbers or my improper method it would be appreciated.

Look at WWW.wallaceracingcalcutators.com put in you numbers and it will give you your new compression.
