Then the best you can do is guess. Add 25-27* to your IVC and use that number as a general range of DCR. What kind of cam is it? Does it have lobe numbers on the butt?
EDIT, just saw the other post. Being that it's a Flowtech cam from Ed, you can get the .006 duration from him. Either way what I stated above will get you very close.

Thanks. That was the idea. I just made J-Rod's calculator easier to understand.

Using the compression figures Ed gave you, your .006" duration should be 298* and you .006" IVC should be 77.

Thanks for all your help guys!

So is the general consensus that at

12.3 SCR and 8.75 DCR this car will be a monster with 93 octane?

Dug, I get 7.8 DCR for yours.
