Talk:Pratt & Whitney R-2180-E Twin Wasp E

Individual Cylinder Displacement
Just a thought, but if the naming convention follows from the R-4360, which was named as such based on it's displacement, would it not make sense for the R-2180 with half the cylinders to have the same displacement per cylinder? Because of this, I am not sure that a citation is needed. I will go find some engine specs otherwise. — Preceding unsigned comment added by ArthropodOfDoom (talk • contribs) 18:23, 16 July 2013 (UTC)
