I rebuilt an SC300 A/T Diff with the 4.27 gears to include a Torsen LSD for my SC400 (stock 3.92 ratio).
The car really rips. The 4.27 LSD alone took 0.4s from my 0-60 and 45-65 times. In general, the car feels 300lbs lighter. It is much more peppy off the line.
3k rpm in top gear is at ~75mph on the highway, and the engine would redline out at 149 in top gear: I'd say that is still plenty fast.
Fuel economy has not appeared to be significantly different as the tach still lives under 3k rpm during 95% of the time I am in the car.
