I don't use calculators....I do an actual pour of the engine....When mocking it up I pour, usually mineral spirits, the cylinder and count the cc's used....Then I use the equation in the back of a Lunati catalog to do it the rest of the way manually....

Your dynamic is fine....you cam change it easiest with a cam swap.....a 114 lsa will have a higher dynamic while a 106 lsa will have a lower dynamic....to a point .....but all the factors Denny mentioned DO affect the dynamic.....

All in all you should worry more about the static.....but remember just because KB tells you 9 to 1 doesn't mean anything unless you do all the measuring and math yourself.....
