340 x-block vs. 410 stroker ?

I'm very thankful distill have my parents with me. Both far away in different states but yet mom doing good dad doing okay. Anyways about to put a whooping on this automatic tranny or it's gonna whoop me, one of the two!

We found out Monday my mother in law has another spot on her kidney so dealing with is a priority. IDK how much more she can take. Cancer and surgery last year, a stroke a couple of weeks ago and now this. It ain't good.
