Chevy S10 Blazer Blown engine

Good condition Blazer but engine is "blown" do not know the specifics of the engine damage. The oil filter was full of metal when removed and opened. The windshield has some rust around it and has minor water leaks. It has been inside ever since the engine was blown so there is no water damage.
The good news:
The Blazer has been well maintained since new. One owner. Very clean interior. Everything worked when it was parked. It had regular services and transmission fluid and filter changed every year, It is stored in a hangar and has been inside for the last eight years. I bought a engine to replace it with from a damaged blazer that had about 160,000 miles on it. The spare engine comes with the Blazer. Best vehicle I have ever owned just no time to replace the engine. Great in snow and ice. Ideal starter for rock crawler or custom modifications. Will assist loading spare engine. Have a fork lift and a cherry picker on location. Also have 4 used rims that will go with the Blazer that I used as quick change snow tires. They are plain wheels and have no tires on them.
