Hi Douglas
Yes - I have driven it myself with the speedo not working a couple of times after cable failures. Also, the speedo could have been swapped at any time. The evidence that the block was originally in the car is based on the engine numbers at the time the car was built - again it is always possible that it was swapped later. So, yes, speculation. But what else is there to go on?
Having been told above that cars might do up to 100K without a rebore - seems that the block may have been sleeved before it reached its 4th rebore at -60 thou for some reason? But perhaps many cars were not so well cared for and needed more frequent attention?
