Crate motor 225 ?

Back in the 90’s I won a contest that was sponsored by the Dodge dealership I bought my Challenger from and the local newspaper. My winning was $2,500.00 in the form of a down on a new car, service work or parts. So, I decided I would order a virginal 225 long block. They were skeptical at first then called me in 3 weeks that they had found an engine for me in a mid-west warehouse set to be delivered to a military base. According to the dealership this engine had never been installed in a vehicle. Since I had the won monies on account I was charged an agreed $1,100.00 when it arrived. It arrived in the parts dept. strapped to a pallet. Out the door charge was $900.00 for the 225 1977 long block. What would you call this engine since it had never been installed in a vehicle. It is now in my car with 125K miles on it. Thanks, Al
