Series 60 11.1L, 12.7L?

[birds_first]

Which engine do we have in a 95 WB is it the 11.1L or do we have the 12.7L? I can't locate a data plate. TIA

Thanks Randy & Peter, now for a better question why are there 3 versions of the 60 Series, 11.1, 12.7 and 14L?
They are all 60 Series, just wondering why Detroit didn't use a different nomenclature for each version???

Marketing... people like the series 60 so they want to keep the name to sell engines... they essentially have the same architecture, just getting larger... Detroit wanted a larger engine to compete in truck market... Freightliner and Detroit partnered on the 14L. The 11.1 liter engine was a bit small for the truck market, many bus companies liked the 11.1 because a little bit better fuel economy.

Here is an interesting article, does not really address the 11.1 but explains the differences in the 12.7 and 14L engines:
