Is it possible to just change the final drive in a 340 gear box?

only asking for reference if i go down the tuned 16v route would be good to have longer legs at the top end!

anyone?

I'm sure the final drive as per most Volvo's is 1 - 1

Your best bet would be a taller diff

the 4 was 1-1 and the 5 a overdrive?

ok so whats the best way to get higher gearing?

what has a taller diff that will fit?

I think the carb 360s had the most long-legged diffs, something like 3.26 or 3.36 ...

Yep GLE's had 3.36 ratio diffs

and what was the diff ratio in a carb 1.7 340?

3.64 I think... same as GLT's... others can confirm for sure

Tis indeed! You'll notice the second gear hole a lot more with a 3.36, I notice it more in a 3.64 vs a 3.8x.

I've found the post I had in mind:

Some time ago someone posted a full list of all teh different diff ratios. Does any have that list?

I do, but I can almost remember all the options.

Unless you're using this setup on the motorway all day, I'd stick with the 3.82, seriously. It's ideal for a revvy NA motor which is relatively lacking in power. Save the big gears for something with bags of torque.

I've just gone from a 3.36 (standard 360 carb) to a 3.82 (340 1.4 5 speed) in my 360, and it's a big improvement when driving 'for fun'.

cheers
