Before you try this I want to see if anyone has any better ideas......

As I see it you need to ....

#1 reestablish TDC and cam position....and it appears you have valve contacting piston at this time..

#2 you will need to reestablish IP timing...

now this is what I would do....however lets see if someone has better ideas first...

#1 I would check by what valves are open and closed to dtermine which stroke engine is currently on....if its on the compression stroke you are in better shape than if you are on the exhaust stroke.

If its on the exhaust strokeI would pull cam spkroket and unbolt cam towers...this will allow all vavles to close allowing engine to be rotated to TDC if its not there already...gat the cam into the correct position and reinstall.. you will then need to rotate it to 14 degrees BTDC .but then you need to pull the IP and get it back to the proper position by lining up th emissing spline with the mark, then reinstal (and then doing the drip timming to get precise)

If you are lucky and its already on the compression stroke you reindex the cam with the crank at the correct position for TDC..

then before you touch the IP see if it starts and runs..if it does great...if not then you need to get engine to correct stroke at 14 degrees BTDC then pull the IP and reindex it reinstall, then do the drip timing. If it slipped on the crank sproket you will need to reindex the IP.....if it jumped on the cam sproket then you did not disturb the crank to ip timing reference.

Thats a whole lot of work and will entertain any other ways to correct this condition.
