 Your pistons, your rods, your crank, they have to be very, very strong. Right. Forged. And that's what they did. In fact, I think that's why they went. As you may know, Dodge already had the 6.4 liter engine out there. And I think it turned out that it was going to be so expensive for them to make it more bulletproof with the supercharger on there that they actually redesigned it and went with 6.2 liter engines.
