Ok, so apparently I must not be asking the question properly...
If I have the 4.7 gearset in the front reduction case and stock gears in the rear:
Can I have the front case in low and the rear case in high and drive in 4.7 low range? Or front case in high and rear in low and run 2.28 low range? Then both in low and run a 7.whatever low range? If this is accurate, does it really matter which case has the 4.7?
