I've got an aluminum 4-71 block and it weighs just under 200 pounds.

I think it's a bit hard to look at total weight of an engine. I suppose you can have an aluminum block, head(s), front plate and cover, rear plate and bellhousing. Many times, these were mixed and matched ie aluminum block/iron head, etc.
