The 4.08 's work great with my 7 AT. 1/8 mile in 8.01 seconds, the 1/4 in 12.42 @114.3. Im turning 6000 rpm in 5th.
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.
