4.10s, 3.73s and RPMs

[95CobraStang]

I was wondering what kind of RPMs I can expect to be spinning at 70mph with a 95 Cobra (with 3.73s and with 4.10s). I noticed that my Cobra runs higher rpms than my friend's 94 GT, so I don't think any GTs out there can help me, unfortunately.

I'm in a real dilemma in choosing which gears to run.. Any ideas??

Assuming .68:1 5th gear and 245/45 17 tires:

3.73 - 2321 rpm
4.10 - 2552 rpm

 

[Mrgreen94gt]

About 2291 rpm with 3.73.

About 2518 rpm with 4.10.

(Considering that 94-95 Cobra had 255/45-17 tires)

Not a really big difference really, just depends on what you're going for with the car.
