del-sol 68s

I recently bought a 97' Del Sol. I was told the engine was swapped out. Where do I find the engine model # ? I want to purchase some aftermarket mods and can't figure out what engine is in this thing. Any help would be greatly appreciated....

be careful though, heads can be swapped. Blocks can be swapped.
just above the header is the head casting ID and date.

It says D16Y7. Also 2312590. If that helps...

D16y7 is found in Ek DX/LX models and 96+ Del so S models.
