Gear ratios & highway speed

[motto (RIP)]

I operated my Lease-Lend Chev for many years with a Five speed OD box from a CCKW. I found that it was not a success with the 216 as that engine just didn't have enough grunt to pull 5th gear except under favourable conditions. The 235 engine (still a splash feed) made all the difference but even then I could have used a few more cubes.
