Reman engines are usually used remachined engine blocks, reground and/or polished cranks. Basically anything that has a core return. Just about everything else internal is new. Cylinder heads will be used reworked castings with new valves and overhead. Injectors probably rebuilt. Remans generally only get the parts replaced that need be. Otherwise a “new” crate engine would be north of $60,000. At least that is my experience with them.
It has also been 16 years since Cat has cast a truck block so finding a virgin one may not exist.

I thought the new content engines had a new block, head, and crank? A guy in KS that my brother hauls cattle with got a new content Cat and is currently arguing with them about an overhaul at just under 40k miles.

Warranty doesn’t mean they won’t fight you on an overhaul.
