Displacement is just the total volume of the cylinders of your engine. Remember that the volume of a cylinder = pi*r^2*h. When calculating engine displacement, r=half the cylinder bore, and h=the stroke. Then, multiply that cylinder volume by the number of cylinders for the displacement of the whole engine.
Today, all manufactures use metric units (liters) rounded to the nearest tenth of a liter, whereas American manufactures used to use English units (cubic inches). When calculating in metric units, calculate with the bore and stroke in units of centimeters to get volume in cubic centimeters. 1000 cubic centimeters=1 Liter.
The conversion between cubic inches and liters is roughly 61 cubic inches in a liter. So, a 327 cubic inch engine would round to 5.4L (more precisely 5.36L)
Not sure the exact cubic inch figure for the 3.6L Camaro, but depending on the rounding error in the 3.6L number, it must be between 217 and 223 cubic inches, probably on the low end, since most metric designed engines round up. For example, my Alero's 3.4 is actually a 3.35L, and my Mustang's "5.0" is actually 4.951L.

Careful on the rounding errors. The LS1 is actually a 346 (5.67L), if I recall correctly, and the LS3 is a 376 (6.16L). Not sure on the LS7, but for some reason, 427.6 (7.01L) sounds familiar.
