273 Radiator for 340?

3 months later.....I wasn't able to get that radiator but I did get this one. Drove stupid far to get it, price was okay at $90 tho. I'm taking it into a good radiator shop to see if they can re-core it adding a third row. I'm wondering if there's anything else besides adding the third row that I can enquire about to make this radiator have the max cooling possible. One thing I'm wondering is about offset rows, does that get more air onto more fins and is it something that can be done with these radiators? Any ideas or comments would be appreciated again looking to cool 350-400 Hp. Thanks.
