I am looking for tall gear sets for my 8.8 Ford in a 03 Crown Vic and for my 10 Bolt 5 lug G20 93 Chevy Custom Van.
For the Ford I found that they made these gears sets: 2.26, 2.47, and I think something around 2.56.
And I am looking for the closes to those numbers for the Chevy.
I am hoping someone here can help me.

WHY?? I plan on running 6R80 in the Crown Vic and a 8L90E in the van and with the super low lower gears will have the same power at take off as the stock transmission and rear end.

3.08 final ratio is the modern one it will put you at 1600rpm @ 85mph 0.65 8th) gear
2.41 is the lowest you can go but you risk stalling the engine
you can lower the ratio further by putting taller tires...
All possible differential ratios above 2.73 can be swapped without having to change carriers (except for the truck differentials with 30-spline axles).]
your acceleration will stink with anything below 3.08... you will probably end up wasting more gas. in the long run
So unless you got a diesel engine or electrical motors to back up that ratio lower then 3.08 final (low end torque and electrical or diesel motors have a ton a of torque )
so i suggest the 3.08 with the "taller tires"
