47-55.1 Radiator

[Root2812]

I am hoping for some guidance here. I have a 1950 with a 5.3L but the water pump has been swapped to the LS3 water pump. This puts the upper hose really close to the throttle body. I need a radiator and wanted to go with Champion like so many of you have but I don't know if their radiators will work for me.

My issues I am seeing is that the center inlet on the radiator would make me have to snake my upper hose around the air intake which doesn't seem like it would work with them eventually rubbing. Then there are the hose sizes and steam ports. The Champion doesn't look to have steam ports. I measured my waterpump inlet and outlets and they seem close enough to standard sizes (1.3 and 1.55 inches measured with a caliper).

Who of you have used the LS3 water pump and what radiator set ups did you use?
