Tahoe has changed the engine block
Is this correct.... the Tahoe engine block was changed back to cast iron
because of melting issues with aluminum block. I think this is what a mechanic
told me. He said to buy a 2013 or higher because of this issue.
I was told this just in passing a while back when I was not looking so now my
memory chip can't remember for sure what he told me.

Your mechanic likely lives in Colorado and has puffed on too much weed. Read about the 2015 Tahoe all aluminum engine at the link I posted.
