Thumbs up

Are you locking the converter on the 2-3 shift? I picked up 3 MPH from doing that in my old LS1 car. A 1.6 sixty is damn good for a 4000+ lb car. I doubt you have a really loose converter in it either.

I think for the first time out, it is running really well. I went 11.48 @ 121 the first time out with my old 2000 Z28. A dozen passes later and it was running 10.70s and trapping 4.5 more MPH. Give it time, feel it out, and it will go faster in no time. The proverbial "learning curve" of a new combination.
