Agreed and disagree.
Sorry, I quoted the wrong fella here. I was actually thinking I quoted fishmen
For the sake of stopping this quicker, my argument isn’t knowing or not what the op stated he wants nor is it to get him to do it but argue it can and has been done. Streetable or not is driver dependent.
Your saying it can’t be done. OK
Tell that to the NASCAR Dodge truck series team limited to a 9.0-1, 358 engine that makes over 700 hp.
And now I’m done here on that.
Now! If “I” were to look for a 600 hp engine and make use of a B big block, I’d look to stroke that 400 for sure. So, that ends my suggestion and point of view it on what to do with a B-400 block for the OP short block wise.
Only if you can’t feed it or cool it.
