340 7-blade fan rivet missing

340's usually came with a torque drive fan. Did you change it to the fixed unit? I am considering doing the same thing. What are your thoughts on it's cooling ability.

This H code Demon was a drag car when I got it and came with the fixed fan. I figured if it worked for him, I would just leave it. Since I'm replacing it now, I'm on the fence as well with the factory radiator.
