Radiator that will fit my 64 barracuda for a 340 upgrade

I am leaning towards the 3 row. The 4 row feels like overkill for my 340.
I have a stock mechanical fan now, and a pusher electric fan that kicks on when the AC is on. I'll start with that.
If it over heats, I'll replace the mechanical fan with the Derale shroud and fan, with their variable speed fan controller.
I put that setup in my 1965 273 and it worked fine until a loose connection board defect popped up in the controller.
[It's being replaced under warranty as we speak.]
Thanks for the comments guys.
