Can you even put the fan blade on backwards?

I don't think I did but is it possible to even put the fan blade on backward. I'm using the original 20+ inch 7 blade A/C fan on my 73 400. Just curious because of the overheating issues I had, and everything else in the cooling system checked out ok. But it's probably the timing off because I know it is. But I just wanted to check everything and I wasn't sure if you can even install the fan blade backwards. Looking down from above the radiator the part # is towards the grille, and the large flat surface of the rivets attaching the blades to the fan are facing towards the grille too so I think it's on right.

Fan blade should say "engine side" on it...got a pic of how it's mounted now?

I thought I had one but I guess I'll have to take a picture. It's the original A/C fan so it's a Mopar fan. If it said engine side on it than it must be on right. But just to be sure, I'll take a photo.

I tried to take picture but the size is too big. I dont think I have any kind of program to shrink them. So I will try and lower the resolution.

Even if the fan is on backwards it will still pull air the same direction.  It won't be efficient and will probably sound like a jet taking off.  Hope you find the issue, cruising season is coming.
