Kind of a loaded question. Like Dave, I'm a racer at heart, and even though we are talking about street cars, I'm guessing he's much like myself and enjoys making our street cars run as well as they can.

As far as what would be quicker really depends on how the rest of the car is setup. The car I did my swap in, was already setup with a perfect working 400 turbo and a nice Continental converter. Going to a 4L80E really didn't change anything as far as performance, it's identical in gear ratios. I simply added an overdrive and lockup converter.

What it does provide me with though, is more accurate and consistent shifting with a programmed controller, and I now have a lockup converter which almost acts like another gear, and can be locked on full throttle runs at any point I wish, which should affect ET and MPH.

It's going to depend a lot on the rest of the car and what you're starting with.
