I see that Dart has released specs on the Aluminum blocks. see www.dartheads.com
Looks like the 351W Aluminum block is 93 lbs for 9.5" deck height compared to 195 lbs for the cast iron version. I have not heard of price or availability. I would guess it is on the order of $1500 more then the cast iron. That would mean that an all aluminum 351 could be made for ~365 lbs. Wow!
