Well I found an S2 engine Saturday. Unfortunately it was too late in the day for them to pull it so I had to go back yesterday afternoon and pick it up. Got it home, washed it, and started taking it apart. Everything looked in nice shape! Got it down to the block, and ready for a final cleaning then fabrication time! Waiting on some thread inserts from McMaster-Carr so I can fit the transmission adapter plate to the fab block.
