My 3.92 dakota sport sounded like it was going to explode on the highway at 70 mph.. not a very comfortable ride.
The stock rear end ratio for the V8 is 3.47, V6 3.06. I recall 2.73s and 3.13s being common street ratios years ago.
Overall top gear for the V8 is 2.32, 2.54 for the V6. The V6 has a 3.59 ratio first gear where the V8 has a 3.0 .
The STR8 uses the V6 transmission with 3.70 axle ratios.
Wonder if you could plug in the 3.70 STR8 Difs into the the base V8 housings? V6 housings? Quite a bit of difference between 3.47 and 3.70 gears (near 7%), it may be worthwhile.
Another trick is to use the smallest diameter tire you can get away with.
On the other hand, wonder if it would make more economical sense to just sell the base WK2 and buy a STR8 (if you can get one) rather than screw around with updating base? Bigger engine, more power, better gear ratios for stoplight racing... warranty in place.
