The numbers I used assumed you had the VV101 cam. The calculator says to use seat to seat valve timing numbers for best results but the closest I could find were valve events @ .020" lift using this site for reference. That means that dynamic compression is actually a bit lower.
Using the numbers for a VV71 it works out to 8.90:1.
Yep that's my favorite calculator except that everything is in some units made up based on a mythological kings thumb ferfawkssake.....
What's nice with that is you can keep banging in numbers till you get dynamic up to high 9s maybe 10:1---then see whatchoo need for "static" to get that number.
