The fans being off the bottom shouldn’t cause a real issue imo, the Intrepid fans I’m running leave 3-4 inches exposed at the bottom on my SS and I haven’t had cooling issues so far.I drove it around a little bit. It didn't really climb past 190 until I got on it. And after that I think it stayed around 200 or so. it might have come back down if I kept driving it normal I'm not sure.
I got home and it sat at what I believe is 175 after idling a few mins.
My only concern with them is they sit away from the bottom of the rad about an inch. They might not be getting enough air pulled out.
I'll get the air box Monday and see what happens after that. I might just have to get a Lincoln fan.
The GN airbox and deflector should feed air into that area.
