Whats everyone's thoughts on B/500

This combination uses a long 6.76 440 rod. And uses a very short piston. So naturally some piston slap . a fairly good rod to piston ration 1.628. Bore to piston ration of 1.05. Seems the word on the street is they will run very well. But they are hard on rings and pistons. What yalls experience with this combo
