The W58 and R154 final gear is not too much in different. They should not be too far apart.
R154 Ratios:
First Gear: 3.250:1
Second Gear: 1.955:1
Third Gear: 1.310:1
Fourth Gear: 1.00:1
Fifth Gear: 0.753:1
W58 Ratios:
First Gear: 3.285:1
Second Gear: 1.894:1
Third Gear: 1.275:1
Fourth Gear: 1.00:1
Fifth Gear: 0.783:1
Reverse: -3.768:1
If your overall wheels is bigger than stock, you should be going fast than what your speedometer indicate.

come on guy's and girls there is a little thing called a speedo "gear drive"
they come in different colours acording to the ratio needed.
we have an electronic speed sensor "Vehicle Speed Sensor" mention in a previous post which is calabrated to the r154, a341, a340 boxes.
the only 2 diffs in the soarer!!!!!!!!!
v8 3.9
tt 4.11
i can put a tt box in my v8 and the guage will still see correct revs but the speed would be going faster than it should.
to get around the difference geardrives and the given pulses it sends to the cluster is to use a Speed Sensor Calibrator.
some cars us the sensor on the gearbox, gauge cluster, ecu, or a combo of any of these.
@ 4000 in 5th you should be doing around 160kph - 100mph
seems like that you need to change the drive gear in the gearbox.

My 5-spd swapped 92 SC3 runs around 3,000rpms @ 75mph on the factory auto diff (18" wheels)....the w58 was out of a 93 SC3. It's def not as bad as I thought it was gonna be.
I swapped out the computer and gauge cluster for the 5-spd units as well though.
