Quote: According to a very vocal engineer on another large mopar site, to make an aluminum block as rigid as an iron one means it almost weighs the same when its all said and done. You need X amount of aluminum material to = iron strength, and it's apparently quite a bit.
For the cost and 100# savings, I can see why they've been avoiding it.
Regardless, I am sure this is the last iron V8 from Chrysler as weight savings is the name of the game now, costs be damned.
As we used to say in Baja, "Aluminum may way 1/3 less than steel, but it's 1/3 as strong."
