Propeller with only 5 blade

[Giraudier]

Hello vanners,
I just notice that the engine of my B350 van have only 5 blade instead of the usual 7 blade!!
Is someone can confirm is it normal or should I change the propeller?
Thanks in advance for your advice,
And sorry for my poor english but I am a french native.

What year is your van, and what engine does it have?

I'm guessing here, but maybe the 7 blade fan is part of the "heavy duty cooling" package.

Sorry I didn't look at your post very carefully......'84 with a 318.

The van is equipped with the heavy duty package but the 318 engine is equiped with a five blade propeller, is it normal?
Thanks in advance,
