Cylinder volume cc

Post by karter13 »

Question : when asked to input a cylinder volume in cc
What do you use.

Excample 3.8 Buick displacement 3800cc

Advertised 3800/6 or 633.33cc
Actual 3791/6 or 631.83cc

Does it matter and why?

If accuracy matters at all re the results of the ensuing calculation, actual engineering numbers rather than sales department ones should be used.
