Everything is pretty much stock and my door tag says I have 2.73s though I doubt thats the case. By the way its a 5 speed. At 60mph my rpms are about 2300. On my old 5.0 which was an automatic I could cruise at *70* and only be at 2000 rpms. Not sure what gears that had though. I would assume 2.73s since it didn't feel like it was that peppy.

If anyone knows their cruising speed and rpms that would be great!

Thanks!

It sounds like 4.10 or 4.30 to me.
