83-88 all the 2.3 motors will directly swap with each other.
89-97 the blocks went to a smaller main journal, and obviously smaller main journal crank.
89-94 engines can be swapped into your 83 with minimal modifications.
95+ engines are a different animal. Same blocks, but castings changed a little. This would not be your best choice to switch too.
Your head will bolt to any Lima 2.3 block.
