My 1986 Volvo 340/360 owner's manual tells me, p 101:

Reduction ratio, final drive

5 speed 1.4 litre models 3.82:1
4 speed 1.4 litre and GLT 3.64:1
1.7 litre models and GLE 3.45:1
2 litre* carb models 3.27:1
*(2 litre low octane models 3.64:1)

The gearbox ratios are the same for all configurations, except some havea 5th. No mention of diesel.

I'm wondering if all the 360GLT models had the 3.64 final drive, or if the older, 84/85, leaded models might have had the 3.27. Anyone know? Is the diff very similar to any 240 series Volvo? I wouldn't mind swapping my 3.64 for a 3.27, 11% faster at same engine revs. I know it's not as good for burnouts, but more relaxed cruising, better economy, less wear.

Here all post 87 models had a 364:1 GLT final drive.
Pre 87:
B 200 K 3.27:1
B300 E GLT 3.64:1
B200 E GLE 3.45:1
The Diesel has a final drive of 3.82:1

on the dif casing there is a little sticker with the ratio on !!
not a 100% sure,hold on.......(/me runs outside and crawls under)....
its a 3.64 in my 83 b19e glt !!!
trying running some different size wheels and tyres !!??

That's what should be under your car...

3,27:1 B200K up to -86
3,36:1 B19A, B200K 1987-> and 360GLE 1983-84
3,45:1 360GLE 1985
3,64:1 B14 with M45R, B172 with M47R, all injected models except 360GLE up to -85
3,82:1 B14 with M47R
4,51:1 B14 with CVT

I'm surprised by that diesel drive ratio. I thought it might cruise at 100km/h at 2000rpm or something.

Dunno about having 11% larger diameter tyres, might have a few probs going over bumps. Maybe raise the suspension, could make an off-road safari 360GLT...

So is there any chance of a 3.27 ratio being on an earlier 360GLT?

Could a crown wheel and pinion be found in another Volvo? 240 or something?

Is the diff assembly similar on a 240?

Looking at the numbers I think 3.64 is 40/11 and 3.27 is 36/11 (crown wheel teeth/pinion)

I have thought my 360 could do with some longer legs in 5th.

Was the 2 litre carb model with 3.27 final drive very common? Any opinions?

You won't find a GLT with 3.27 diff. They just did not build them.
The B200K models are pretty common. All non injection 360's up to 87 have them i think.

i have a 3.27 c/w + pinion (and a 4.7 )and would never think about using it if you wanted it !! a whole unit would be easier to fit though.....

hehe ,yeah sorry brad i didnt notice/forgot

" Location: Melbourne, Australia "

I know someone who goes to UK every so often.

Or maybe you could post them to me?

What do you think they weigh?

The pinion and c/w did live together in a housing? I mean, they're not in a big bucket mixed up with dozens? You're meant to keep the pair together.

yup 36/11=3.27
the c/w is still on diff ,but no housing, so pinion is seperate. my brother snapped a casing in half ,so we used the 3.27 casing. dont know what the weight is,but can find out and shipping i havent a clue what the cost would would be. £50 or £60 ??? [/img]
