Block material: cast aluminum
Cylinder head material: cast aluminum
I wonder what was skipped that the customer will have to deal with?
All aluminum block? Yeah, that will hold up in a full size truck for 200k miles. I am sure glad I bought the old Silverado !
Aluminum blocks are old technology, and they hold up just fine. GM is finally spending a bit of money making a modern power train.
When I buy a new truck I fully intend on keeping it 10-15 years and I don't foresee any problems that my 05 didn't have, maybe less.
