The Stovebolt Site Forums The Shop Area Engine Shop Consumption differences between a 216 and a 235

So, not to change the subject (slightly), what are the same opinions on a 216 vs. the LOW pressure 235, ie: the one available for the '41-'46 Art Deco Heavy-Duty trucks? Since the difference is just slightly more power and displacement, that maybe just a small hit in fuel consumption?

My '41 fire truck was probably born with the 235, but has a rebuilt 216 in it now.
