Reply to "RPM for highway cruising"

Jack CrosbyHot Springs, AR, VS RabyTypeIV

Ron, This has been talked about a lot here---you can see more if you will do a search.

You are seeing 4,000 at 75 MPH . At 75 I'm doing 3,200.
At 4,000 RPMs I'm doing 88 MPH.

What are your specs? Mine are:

Tire height, 25"
R/P 4.120
4th gear .821

Mine was set up for long highway drives but it's still plenty peppy around town. I don't drive around in town in 3rd as 4th is plenty strong and doesn't lug the engine at all.

I wonder what your specs are. Also, maybe you aren't getting a real accurate speed reading?

What is your highway MPG?
