This COOL little Java Applet lets you figure out your Displacement, and/or Compression ratio. If you would like to know what CC's or what Deck Height will get you a particular Compression Ratio, it will solve that for you as well.

Engine Item	MM	Inches	Measurement
Engine Bore
Engine Stroke
Deck Height *
Combustion Chamber CC's
Your Compression Ratio is
Number of cylinders
Your Displacement is :

Solve for which variable ?

HELP ME

mm to inch conversion (Just for fun)
mm	inch	fraction

Enter a value in either the mm or inches box, then click the mouse anywhere outside of that box, and it will instantly calculate the other values for you.

* note: The Deck Height measurement is from the top of the block or cylinder down to the top of the piston, if the piston sticks up above the top of the block or cylinder, the deck height will be negative ( -.010") Remember to figure in the thickness of your headgasket (if you have one) into your deck height. (if your deck is -.020, and your head gasket is .100" thick then your deck would be .100 + (-.020) = .080 ..... get it?) If your deck is -.100 and your head gasket is .050" thick, I think you may have a problem. .050 + (-.100) = -.050

* another note: If you have pop up pistons, you will need to measure the cc's lost by the dome of the piston and subtract it from your Combustion Chamber CC's measurement, or add the cc's if you have a dished piston.
