Found 1968 383 "S" engine

As some of you know, I recently bought a 1969 barracuda with the A57 'cuda 383 package. I do not have the original engine but it came with one complete engine and 2 cores. I have discovered the engine I planned to use in the car is an A-Body 383. If you are restoring your car or have restored it and this is the engine from your car, I would be willing to work something out with you. The stamp is 8B224466.
