Why some hipos have 4 blades fans and others have 6 blades ?

Good question. Mine had HD cooling but still had a 4 blade. Ac on my Swinger got a 6 blade although the Ac unit was Mopar but dealer installed. No clutch fan or shroud either.

Do you have the build sheet? I see several different sales codes and cooling packages.However, my Govier book does not go into detail about fan blade-count.

This is the setup I'm going with
6 blade and a shroud and four speed only radiator
I'm doing a 1966 S build
The 1966 hipo I got came with a four blade
I've seen Hipo pics from sales brochures and stuff with pics of both four and six blades

interesting question. I also wonder when the clutch fan came into use?

I first see it listed on 340s, so 68? IDK.
I am also running a 7 bladed fan, factory shroud, and a clutch! I had all of the pieces on hand, I just put them together!! I recently made another identical fan for a member here, but had to mill out the center for the clutch, whereas mine was already done for that!! Of course, now I'm keeping an eye out for the 7 bladed fans either already milled or millable! If it has a center with round holes, it can be milled for the clutch, if it has slotted holes, not going to happen!!
Top pic is my fan, lower pic is the one I made for a member! Same/same!!

Those fans will cool any sbm to 450hp at least, depending on support works of course.
I have the build sheet. HD cooling (AC radiator) but 4 blade fan. I have a clutch fan to go on.

I know I'm right....
65 "S" LA build 6 blade, no shroud, no clutch no A/C, but had P/S. Now its a Meziere w/Electric puller on a Cherokee Chief 28" radiator.
So if I understand what you're saying, you take a factory 7 blade fan that has 4 mounting holes (not slotted holes) and center register, mill out the center to fit a clutch fan. Interesting! I might have to try it when I have some spare time (yea right!) as I probably have 4 or 5 7 blade fans sitting around.
Yes, that's what im saying!! I'm also saying "bring those 7 bladed fans to the Nats and I'll buy em all"!!!
OK I'll keep 1 for the wagon and 1 for the Barracuda and bring the rest!

Hey - I'd take one of those fans - where are you going to be at the nats ? are you in the swap meet ?
To answer original question:
"Why some hipos have 4 blades fans and others have 6 blades?"
The '66 service manual has all of the details for each engine package. It has fan, clutch, pulley, radiator size & which has a shroud. I can't find mine right now so I can't post the chart from the SM.
