Fixed cooling fans for a 340

the pitch on the 224 is 2” & 226 not sure as I’m still trying to find the spec.
So would more pitch mean greater cooling effect?

More the pitch, more air it moves and more horsepower it sucks up.

You have to think of it like a boat propeller, the distance it moves through the water in one revolution. That is what the pitch is.
