3800 is actually a rounded number... Just GM'* way of setting apart the xx00'* over the x.xL engines. 3400, 3800, 3900, etc, over 3.4 3.8, 3.9...
Depends on how you look at it. Perhaps GM is just switching to CCs to differentiate their redesigned engines?
Yes 3800 is rounded, just like 3.8 is and 231 is. Motocycle manufactorers often round to the 50 or hundred CCs, even if their far off. Some manufactorers even cheat on their rounding. The famous Ford 5.0 is actually a 4.9, the Mercedes AMG E55 is actually a 5.4. Buick old Nailhead 401 wasoringally known as a 400 because of GM'* engine restrictions.
