Got ahead of myself. I took 3 hours today removing the motor and changing the sump over from 1.3 to 1.6. It was quite obvious where the rods had been hitting. But it was a very subtle noise, not a loud banging like others have described and the scoring on the sump was rather minor.
So the motor is mounted back in the car and bolted to the auto. all that's left to do is fix the drive plate to the ring gear, bolt on the manifolds, starter, generator, radiator, etc. Not much really. I might get back down there tonight and finish it off. At least I know now that everything is sorted and I can just get on with driving the beast. Can't wait!
