Champion radiator - I cut her open

Cut the top and bottom tanks of my old champion radiator that was in my 440, 67 barracuda.
The cores are tiny. I could barely fit some 0.6 MIG wire through.

This rad was setup with a shroud and twin 1300cfm fans. Still didnt work.
I'm planning on buying a decent core and making a twin pass with some spal fans and another shroud. Maybe 2x low profile pullers and 1 big arse pusher on the front.
Thoughts...
