As YR said above, do you have a tach? If not, you’ll need to at least borrow one. See what your rpm’s are at Hwy speed.

The OD 4spd manual trans has a deep first gear that will allow the car to take off really quick. 2nd & 3rd are normal and 4th drops pretty good. If your not in a good rpm area when you’re getting to the cruise speed, it will feel sluggish.

I am faced with the same dilemma of OD versus non OD, but my car has a 2.xx:1 differential ratio, 13" tires, and a 273 V8. Since I have all the parts, I will install the non-OD 833 first instead of the OEM 3 speed. If I am not satisfied with the 833, then I will install the 833OD.

In terms of engine rpm, going 70 mph on the highway was about 2,000 rpm in my Honda recently; nice and relaxed. I intend to do more highway driving in the Dart than local roads, but I still want the car to be able to move with some gutso on my way to the highway.
