I do not recall if all the tall 5th gear options require the fork machining, I have the 0.642, which with the 4.22 R&P is 80 mph cruising in 5th at 2750 rpm, you gain another 100 rpm for the 0.62.
If you upgrade to a 3.77 and tall 5th the 0.642 provides 80 mph cruising 2450.
Personally I think this is the ideal combination and the 3.77 makes the lower gears more usable albeit at the expense of a start/stop in heavy traffic.
At 70-80 mph what kind of Gas Mileage do you get with those gears?
