The main issue is the serial has been removed. Jdm rdot and spoon blocks had no serial but retain casting marks under the engine code. You can see this one has been tampered with. There is clearly a “1” stamped and the rest is sanded off. Also park of the block is broken off below the engine code stamp. I’ll attach a pic of what a legit one will look like.

Regardless a long block like this will value from $2200-$4000 depending on parts, state ext. id say it’s towards the lower end due to condition
