COMPRESSION RATIO CALCULATOR
Static and Dynamic Compression Ratio
(Considers Cam Timing and Rod Ratio)

Click on link:

http://kb-silvolite.com/calc.php?action=comp

ENTER YOUR DATA CALCULATED DATA
Cylinder Head Volume (cc)  Cylinder Head Vol (cubic in.)  
Piston Head Volume (cc)  Piston Head Vol (cubic in.)  
Gasket Thickness (in.)  Swept Volume (cubic in.)  
Gasket Bore (in.)  T.D.C. Volume (cubic in.)  
Cylinder Bore Diameter (in.)  Gasket Volume (cubic in.)  
Deck Clearance (in.)Note: Neg. nubmer above deck, Pos. number below deck  Deck Volume (cubic in.)  
Stroke (in.)  STATIC COMPRESSION RATIO  
OPTIONAL DATA
Rod Length (in.)   Adjusted Stroke (in.)  
Intake Closing Point (degrees)ABDC @ 0.050 lift plus 15 degrees   DYNAMIC EFFECTIVE COMPRESSION RATIO

I'm hoping that posters will make use of this calculator.,. what compression will I/or do I have, is a question that is asked over and over again on forums.

And then there is this link:

I also like this online calculator a lot:

You can find most data for your engine and calculation at the same page and it's pretty easy to use.
You can either use adv. duration plus lobe separation or intake valve close point to calculate dynamic compression and you can advance or retard your timing and see how dynamic compression changes.
