Builders: Square engine, Over Square, or Under Square for you?

I've never understoof the emphasis that Mopar guys seem to put on rod ratio.
It's much lower in list of priority for proffessional engine builders and race teams.
How ? It's only if you build a stroker Mopar you only have to worry about like 4"+ stroke sbm and 4.25" + stroke bbm and they don't seem to care about it, But there's tons of long rod swap options for Chev and Ford so it would seem they worry about it more.

Is there huge power gains to be had, especially with lower output/rpm engines probably not. But it is one of the advantages Chrysler engineers built in, it's apart of the design, It one of the features that makes Chrysler stand out among the other brands. Is it gonna be the end of the world if you build a 408 and get rid of those features no.
