The diference in rpm is aprox, 700 to 800 rpm more and fuel consuption goes from 37.5 to 31.5 mpg.
2nd gear is the gear of punishment as the car just screams. Now hold the gas and brake at 2200 rpm and launch the car . It becomes a cruise missle. I shift at 7800 to 7900 rpm.
3rd gear is also very powerful and fast.

I think he meant 27/21. Z since you seem to be the only 7AT to chime in on this I would benefit asking you some more direct questions.
How has your SRM been effected?
What is your RPM's at 80 considering this is my average speed in the interstate.
Thanks!

The SRM will be off about 300ish rpm. I have had the SRM shut down from time to time doing high speed runs , typically 120+ speed. I have not installed the gears on an auto yet, but i do know the carrier is different from the auto to manual. So i can to be sure the these gears will bolt to an auto carrier. to be sure you will need to find a manual diff from a 370 or later model 350. I have heard that the diff from the 350s will fit but the pinion flange is different, so that will have to be swapped, no big deal. The gears will make a HUGE difference !!
Also if you need the gears let me know as i can get them at a great price!!

J would you be willing to source all the parts I need to get this done on my 7AT?
Thanks everyone has been given rep that has helped me!
