I had my MOG converted about 15 years ago. It's the best thing I ever did. I remember speaking to a friend of my Dads who at the time was a "boffin" with the MOD. He worked it out how long it would take to pay back the outlay of the cost of the work to replace it. Of course he was working on the fuel prices of 2003! And of course the car drives so much better.
Rev reduction was the main reason for the conversion - to make for a more relaxed drive. However, if I get an extra 3mpg I reckon in about 5 1/2 years it will have paid for itself (@8000 a year)
