5.0L Highway Revving

Ok im curious what kind of RPM's you 5.0L fellas do going 100km/h(60miles/h) specifically anyone with a c-4.

Im doing about 3000rpm with 3.55 Rear Diff.

This seems kinda high to me im thinking there might be something wrong with my tranny. But it seems to shift fine in all 3 gears.

Also if this is wrong any ideas what could cause it?

What size tire are you running? Are you sure you have 3.55, that's not a factory Bronco II ratio.

I turn about 2800 or so at 60MPH

Have a look here

thanx man i couldnt find that chart I knew it was out there :)

I have 31" tires and the 3.55's is what i gots I guess im supposed to be at 3000 cause the cvhart says about 2600 with a manual mines auto so makes sense :)

im just so used to my 5.0L mustang 5-spd 1800 rpm doing 100km/h wich I liked lotsa power like 24mpg at the 3000rpm area its hard to get much more power :)
