Actually, you can determine your engine's ACTUAL  CR by doing a =
compression test. This is not the theoretical compression ratio by any =
means, but the true CR taking into account all the worn rings, bad =
valves, and cracked pistons that your engine is actually living with.=20
 Unless your engine is in perfect mechanical shape, (and has a very mild =
cam) the actual CR will be something less (sometimes a LOT less!) than =
the theoretical, but it will give you an idea.  It only takes a few =
minutes with the pressure gage and a few seconds with a calculator.

  Oh. I thought you guys were talking about cc'ing the combustion =
chamber or something.

  So I can figure out my compression ratio by doing a comrpession test? =
Hey, I have a cheapo compression test gauge deal-io that I have never =
even used.=20

  How do I do this and what should I be looking for?
