Wasnt the engine in the end though. Ended up being the flywheel. Got the engine out and the clutch off and it looked like this:

Currently my plan is to get the head off and see if there is any damage in the engine, but i suspect not. Feels ok when turning over by hand. If no damage then ill pop the head onto another spare short bottom end and race that (with a limited rev range) next weekend before rebuilding over the summer.
More pictures to come from Mallala, and the week leading up to it.
