does anyone know the weight difference between the 5.7l with the 392 stroker and the 6.1 l with the 426 stroker.

I am not talking about the crate engines im talking about stock 5.7 and 6.1s with the strokers... unless its the the same thing as the crates which i doubt.

But if someone can do me that favor and give some insight on the weight differences on both i would greatly appreciate it.
