Tranny & Rear End Ratio Question

[Xmas]

The high 5th:

Gear 1 Max Speed - 50 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 4000 RPM in Gear 2
Gear 2 Max Speed - 76 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 4100 RPM in Gear 3
Gear 3 Max Speed - 112 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 4700 RPM in Gear 4
Gear 4 Max Speed - 144 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 3900 RPM in Gear 5
Gear 5 Max Speed - 224 MPH at 6000 RPM
Cruising RPM at 70MPH in Gear 5 is 1900

Vs the smaller .82 over drive that is this:

Gear 1 Max Speed - 50 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 4000 RPM in Gear 2
Gear 2 Max Speed - 76 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 4100 RPM in Gear 3
Gear 3 Max Speed - 112 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 4700 RPM in Gear 4
Gear 4 Max Speed - 144 MPH at 6000 RPM
Shifting at 6000 RPM puts you at 4900 RPM in Gear 5
Gear 5 Max Speed - 175 MPH at 6000 RPM
Cruising RPM at 70MPH in Gear 5 is 2400

I'd prefer the mallee 5th. I like the 3.31 though
