It just goes on and on and on. Start a post of their own and have at it with every chart, graft, YouTube videos, calculations, formulas, etc. but it’s never on a post they start.
I don't have any vested interest what the OP builds, whatever he feels best suits him, for better or worse, best we can do is lay out realistic pros and cons and then it's up to him which way to go, then try to help him get the best out of whatever choices he makes.
He doesn't seem to have any interest in what my next move would be if I was him and I'm fine with that, still gonna try to help with whatever I can if that is to call out this idea you need to do like a Nascar level build to make 500+ hp out of a 340 that's what I'll do.
