AJ30 Jag engine / box install. Gear ratios?

Hi

I'm looking at fitting a Jag 3.0 V6 out of an S-Type along with a 5 or 6 speed manual gearbox.

I could do with knowing the gear ratios as I would then be able to work out what rear diff ratio I need

The existing ratio is a 4.2 (lsd) out of a Sierra, yes this is not ideal but the car was going to be used for sprints and hillclimbs

but now just going to be a road car. The existing engine is a BOA V6 Cossy and MT75 box which will be pulled and sold.

If you are using the Jag Getrag box, a 3.62 will work well, a 3.3 is better for motorway cruising.

I've put in the standard 3.64 that is usually fitted in the 7.5" diff - had the LSD swapped too.

'box is the early 5 speed Getrag 221

I'm using 8 x 17" wheels with 215/45/17 T1R's (may sell and fit Rainsport 3's)

I have a programmable speedo so no problem there.
