I'll look the pictures out in the morning and post them. They arn't the best but maybe of some interest. I still have my first Seven which I've had since '77 and the remain of an others that we are in the process of rebuilding. All the sevens from Steels had L block motors, so I would think that it was swapped outat some stage at a rebuild? but apparently the black car had some head work done by PDL, before leaving the factory.
THe last time I saw your car the body was looking a bit tired and that was before Charlie put it away. It's been a long while since it was last running, possablily at the meeting at whenuapi
