I did some guessing from memory here, but at 6500rpm, you should have been going around 159 or so in 5th. I guessed at the 5th gear ratio (isn't it .82 for a '76 915?). I also used 26.13 for the diameter of your tires, but the actual rolling diameter might be a little less (leading a slower speed).
