340-360 vs 408-414

I've read that Chryslers engineers said that the stroke shouldn't be more than 92% of the bore for best horsepower to friction so a 400's bore shouldn't even have a 4" stroke and all but the 225 /6 don't go over this bore to stroke % and have high rod ratio I don't see you would want to build these features out if you need 400+ CID wouldn't make more sense to build a big block?
