-----------
3.791 liter
3791 cc
(231.341 cu in)

Bored 0.030
---------------
235 cu in according to: www.jepistons.com/Catalogs/Automotive/Buick/Buick.aspx
3.851 liter
3851 cc
0.06 liters larger
60 cc larger
10 cc's larger/cylinder

This is based on my calculations of: 231.341 divided by 3.791 = 61.02. The figures below the "235" cubic inches are based on that 61.02 number. One can use the same number to calculate their motor's liter and cc's if they have the cid size. I'm sure there's a calculator out there, if one has the bore and stroke...I was just "bored" and had nothing to do.

For instance, for a motor bored 40 over (236 ci): 236/61.02 = 3.867 liters.
 
yes, that's all basic math like we used to be taught in school.

and, yes, there are a lot of online calculators out there for these things.
