I'm not far from you at all - Rugby, Junction 1 of the M6.
I recieved the motor already fitted in the chassis - the previous owner doesn't know its history either, all he did was put some oil down the bores. I haven't even tried to turn it over as I've only had the car for just over a week so don't know what conditon its in. It looks cleanish though and the block has been painted blue (maybe has had a clean up and rebuild?)
