FS - S13 Blacktop SR20DET (messed)

not really sure wtf happened with this engine, had 2 different sr20det specialists come look at it. no one knew whats wrong with it.
All i know is slow crank, exhaust cam skipped (when i took the valve cover off)

Sooo i’m going to sell bare block, lets start at 250obo

note:: Engine will be pulled next weds/thursday from the car.
