How much does a Slant 6 engine weigh?

I just relocated a 74 slant yesterday to store out of the rain. Just about pulled my back and bent the metal dolly I rocked it onto. That was with head, intake, and exhaust on. Besides heavy, it is hard to set stable with the assymetric layout. I rested it on the rear end on 4"x4"'s. Stands much taller than the V-8 next to it. I recall Chrysler was very proud that their new LA engine (273) was only 50 lb heavier than the six. Would be great if somebody made an alum head for the slant, but maybe after pigs fly.
