Which one flows better, factory 6 blade water pump or 8 blade

AJ, the picture is what my fan set up looks like. It is a seven blade fan off a 80s dodge truck. Is this a good fan?
I have a Hayden 2947 thermostatic fan clutch and a new cold case radiator, and a stock 180 t stat. My shroud fits very tight and contains the whole width of the fan.

It goes from 190 Cruising to 230 idling with the ac on after a few minutes. I don’t know if it would go higher, I stop it because I don’t want to over heat.

I bought a milodon t stat I have not installed yet. It is a pain to install with factory air. If this doesn’t work, I think high flow water pump is next?
