Just another point of view, I have a VY SS 5.7 Manual 6 speed, and I find the standard diff way too tall for a big car, (about 3.7, I think), Great on the freeway 100kph in 6th, only doing 1500 rpm and 9lts per 100km's But the problem is towing a 1.5 tonne trailer. Handbrake start on a bit of a slope, I've got to really ride the clutch to get it to move. Not that anyone will be doing much towing in a Cobra, but I am looking forward to my R33 4.1 (.3) If it's too low, I'll just use second gear to start. Should do nice burnouts in first, though!
