V8 Swap Radiator

Hey guys,

So I'm just getting everything together to swap my Slant 6/904 out for a 360/904 set up. Will be using the Schumacher conversion mounts to do this. I am under the impression from what I've read and logic that my stock /6 radiator will not be sufficient. I'm having a heck of a time trying to track down an original A-Body small block rad, so I would appreciate any sizing advice and/or specific radiator suggestions. I'm more than open to/preferring aluminum radiator options as well.

Thanks in advance!
