I just swapped out my all cast iron 340 for an all aluminum 528 hemi and was wondering what the weight difference is. I know the hemi is lighter but any idea how much?

It has stage V heads and a aluminum mopar performance 2x4 intake. I have both motors on engine stands and the hemi feels lighter when moving the stands around.

maybe the Hemi is still a little heavier. Hemi cranks are heavy parts!
