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
What stroke you talkin about? If you mean the 4.25, you will need a 6.535 rod. Even then, you will have a 1.322 C Height. That's what I'm using in my 512 build. 400 Block. Even then, the pistons will be a little above the deck.
