2.25 is right

The displacement increase is real, it is from stroke.
Different crank. I believe I read that it was now a 3.48"
stroke, and that gives almost exactly .1 liters more as well.

Ford avoids hyping the V6 so they can sell more V8's.
But I'm happy with the incremental gains they have
given us anyway. We can get more out of it now than
ever imagined!

Simply put, what does that mean, more hp or what?
