cc is the size of the motor, the bigger the cc the power the engine will produce. 2 strokes are lower because thay make equal hp with small cc(aka displacement) Check here and read. http://science.howstuffworks.com/two-stroke.htm im sure somewhere theres a link to the 4 stroke kind also.
I like karts
Rotary Power!
to calculate cc: multiply- (Diameter of piston)x(3.14)x(stroke)
all measurements in centimeters to get cc

CC is how much volume an engines combustion chamber has with the piston all the way down. EX:if you pulled the head off a briggs 5hp you could turn it over till the piston hit bottom dead center and fill the cylinder with 206 CCs of oil because the engine has 206 CCs of displacement.
Incorrect...

Good rule of thumb.

Cc's can only give you a ballpark idea of power that engine can potentially produce.
There can be some major differences between like sized engines.
A Yamaha KT100 w/97.6 cc's produces around 15 hp.
My Lawn-Boy's are 141 cc's (43.4 cc's larger than KT100) and hp range is around 6.5 to 7.5 hp, or about half that of the Yamaha engine.
To use cc's as a reference for power probably will not produce expected results.
Differences in power can be traced back to how engine is inducted or it's ability/inability to breathe.
Port timing (intake & exhaust), crankcase size, squish band, and other stuff are major players and define total output for a particular engine.

There was this one car from the 50's, I think it was a formula 1, that had 16 cylinders, and it was only a 1.6 liter. Made like 800 hp too

I don't think that's right. It should be:
[(radius of piston)^2]x(3.14)x(stroke)
pi * r squared * height
I reckon it's accurate when comparing two of the same type of engines.
i.e a 150cc Briggs vs a 400cc Briggs.

Because that is completely and utterly wrong. lol.
Formula for area of a circle is pi * r squared
Then multiply by height to get volume of a cylinder, which is what we want.
Circumerence x stroke is equivalent to 2 * pi * r * height
