Just a little update on this post. The C-Speed calculator is missing a lot of important factors when trying to get an accurate compression estimate. While best method is to CC and measure as Turbogixxer stated, it is tough to order parts if you have no idea how they will react to you motor. Also not many home builders have the equipment needed to complete such a task. I reccomend trying http://www.zealautowerks.com/ if you are looking for a compression calculator.
