I think one of the few 2” improvement radiators is the ron davis units but they are big money from what I recall. I’d love to give one a try one day if they still produce them. They use two 1” cores vs most others which are 1/2” or less. If it is as good at a three row it would make me moving mine forward easier.
Main issue with those radiators is the information is so old as no one really knows that company well except some niche car racing circles.
