Radiator suggestions

Idk what happened to reply but here goes again.
Everything on the car is fairly new, it has a high flow 160 Stat, fine I tested it. When I'm driving 55 -60mph it is 2800ish rpm so has to be flowing. The 2row in it is maybe 5/8 tubes. The pulleys are both 6.5". The 4row will be here tomorrow so I'll swap and report back. Also I wanted the Trans lines in rad to stabilize the Trans temp,it has a 4000 I think 8-9" converter it's allready smoked 1 Trans prob from overheating.
Sounds like there's more at play here than "just" engine heat.
