CC stands for "Cubic Centimeter". The industry standard is to measure the volume of cylinder heads in CC's. Intake ports, exhaust ports, and chambers are almost always measured in CCs. You will need a buret, alcohol, dye, and a peice of plexi-glass in order to find CC's in a suitable manner. I have done it with just a syringe before though.
If your motor doesn't have bearing problems your crankshaft is probably usable in a performance motor. The journals are the parts where the bearings ride on. These will need to be measured with a micrometer and made sure they are within specifications.
I own this book, and I think it would be a great help to you. It doesn't have much information on the six cylinder, but still general info that would help you.
