but, no matter which rear i get next time, im probably gonna stick in the 3.XX ratios. i like em better never really grew to like the 4.10's (had em for 2 years). i enjoyed them more after the cam was in (rev limit raised another 1k), but still wouldve prefferred 3.73's or even 3.42's.

is the Dana 44 8.5" rear the same as the GN's? or is that another animal all together?
thanks
I loved the 4.10's in my 96 WS6. Even before the cam change. Just made it much more fun to drive. And 6th gear was useful I never had any problems with the rear in that car. Even running 1.7x short times the last year I had it. Never dumped the clutch though and always speed shifted. I guess that's easier on it doing like that

The Dana 44 is completely different than the 8.5" 10 bolt in the GN or 2nd gen F-Body, Impala, etc. That rear was around a long time and can really take the abuse.

Not all gear sets are the same. I used 4.10 Motive gears and ran mid 11's for most of a season. The gears still look new. There's also a difference between street gears and drag gears. Drag gears are softer. They're wear out quicker but will flex from a shock load and not break as easily. They also cost more.

The GN used a GM 8.5" 10 bolt. It has nothing in common to the Dana 44 diff. The GM diff still has c-clips on the axles etc.
