Help on diff gears

[Munz]

Just out of curiosity if my WH Series 1 Caprice revs at 2000RPM @ 100KM/H & around 2100RPM @ 110KM/H what would my diff ratio be?

3.07:1

Is it auto or manual?

QldKev

Has to be auto being caprice... but could be wrong

Nah it's an Auto with a 3K stallie & a stage II shift kit but i don't think that this would alter the revs.

I was under the impression i might have 3.4's in the arse end of the car.

I definitely have LSD & i was thinking if someone installed this as factory option or if it would be an aftermarket or after purchase mod.

vuTobySS go to hitorque on goldcoast they should be able to sort out your speedo for you.

haha i got 6spd with the 4.11 and i sit on about 2k at 110km/h, my speedo on the other hand things im doing 130 (used a gps to work out my speeds)
I find that under 100km/h im 10km out on the spedo and over 100km is 20km+
Would love to get the spedo fixed tho
