    Hi, after some family and vehicle issues we have had to postpone our long term travel plans. Just had the engine rebuilt AGAIN, this time by someone who knows what they were doing. She is a 1916 with original 1600 gearbox, engine revs at 3k at 80kph, this to me seems a little high. To put less stress on the engine at highway speeds 100kph i have considered changing gear ratios without changing the gear box, is it an economical project or would it be cheaper to buy a recond 2 litre box? if so how many mods need doing to fit the box Thanks for reading.

    You can buy the gears from Albins, and get a local transmission specialist to fit them - If you just want lower hwy rpm you'd only need a taller 4th gearset. https://www.albinsgear.com.au/

    We did the 4th gearset in the 6rib for the lowlight (was some years ago now...), 0.70:1 Albins gearset was less than $400 IIRC and about the same to get them fitted.

    1600 has a over drive fourth gear anyway ,it's the diff that is the other way which slows it up.(works harder) 6 rib is a better option getting one could be a small issue.2 litre has a higher fourth gear then a 1600 but it's diff is the other way making it work less at higher speed.

    With a 1916, best to find a 1800 5 rib gearbox.
