Well, I dont actually know what cc it is but just arranged with the guy about getting the series 2 off him it is on classic RR chassis with petrol engine, think he said it was 1971 RR so any idea what petrol engine they had? there is even a brand new ported head still sealed in the box from Turner Engineers with it
if its a 71 rr then that would be tax free anyway, wonder if one could argue that modifying a tax free vehicle with bits off another tax free vehicle would make the points system unnecessary
providing the identity of both vehicles is not retained of course
