I used to own a 2.9 4x4 sierra and I used to thrash that from cold every morning.

After only a few months of owning it the car needed a new camshaft because one or two of the lobes had been worn away, this was blamed on me hammering the car hard from cold every single morning With my new cam in I used to run it up to temp and never had another problem and the same with the 2.9 I had after that.

I always now run my own cars up to temp before nailing them, just because the water is up to temp doesn't mean the oil is though.

My company car gets given death from cold though
