This is one of the better gear/RPM calculators out there for our cars...

That's the first one I've seen with the 3650 tranny. Cool. Heres another that's pretty good: http://www.et-studios.com/motorsports/gears/gears.html

does anyone have a site with the stock rear gear specs for cobra's, specifically a 98?

Stock rear gear is 3.27

The only problem I see with the 410's on a 4v cobra motor is that you have to shift into 4th just before you cross the quarter...Wouldnt 373 benefit you more since you will be accelerating through the gates near peek horsepower range (5 to 6 grand)????????????????? I want gears but I dont think I will ever make up my mind!

no 4.10s are the perfect street gear....I street race more than i go to the track so it is optimum for me...I had 4.10 in my old 5.0 and loved them to death....really helps 5th gear out.
