I don't have a dog in the hunt with this dumbass argument, but, as I said in an earlier post, Hensley Motorsports has been building 318 4" plus bore crate engines for about thirty years. They do sonic testing and only use those that are thick enough.....and there are some that are thick enough. This has been common knowledge for a long time now.
That said, I kinda agree with your assessment about this thread being somewhat a "fantasy", in fact, I've already said as much talking about the little box he put it in.......BUT, it's HIS box and HIS thread and HIS rules. Let him have fun. I have a slant 6 box. I have fun with that. You have fun (I hope) with what you do.
His point was plainly explained in his first post. Nobody likes everything or every scenario. Even I don't see the sense in some of his boxing in......but damn, it's his hypothetical reality. .....and staying within his parameters, he's right.
