Aluminum slant build

At one time I had five aluminum 225s (now down to two). I used to like to call up the machine shop, tell them I was bringing in a Dodge 225 slant-6, and then walk in through their front door carrying the block in my two hands and say "Here's that Dodge 225 I called about; where do you want me to put it?". :lol:

So how much DO the aluminum blocks weigh?
