Gears

Rosco · 03-18-2002, 11:52 AM

i'm sure I have 2.73's in my car, running 55 mph at 1500rpm. I am looking to get 3.55's in my car and I was wondering what rpms they would run at 55mph. Or how about any other gears if anyone has an idea. Thanks

I think I am running about 2000 rpm at 60mph with my 3.55's

I'm running 2100 at 55 with 4.10's with 5 speed.

Auto in OD with 3.55 is about 1950...at ~70 mph.

Ok so somewhere around 2100 with a 5 spd? And where would I be able to get the new gears so my speedo isn't all screwed up?

I used the speedometer gear kit from mustangsunlimited.com they have it all right there. Good luck. If you need help just ask.
