I totally agree with Mach 1.
In my AOD car, with all of my mods, I still have a hard time beating bolt-on improved 5.0's with T-5's. I feel exactly the same way about my tranny as Mach 1. It's holding my engine back to the tune of at least 1/2 second. And that's with converter, 3.73's and a shift kit.
On the other hand, my car will pull away from any T-5 off the line...but that's it. After that, the AOD takes too much power to turn. The T-5's are getting a good bit more power to the wheels.
Just out of curiosity...how much better would a C-4 be in comparison to a AOD??
