Either work through all of the thermodynamic equations that prove what you're saying is true and post them up here, or stop making those claims. I'll even do you a solid and just let you work through the math for 2 and 3 row radiators that will fit into an A-body, because I know for a fact you can't prove what you're saying is true for all applications (there's a reason why 3 and 4 row radiators exist). You're a vendor, so I would think that you'd be able to get ahold of all the specs you'd need to do a full thermodynamic analysis.
