Scared to go from Yank SS to the PT
Sacramento has this goofy rule on Wednesday nights that you’re not allowed to run under 11.5 seconds even with a roll cage (which I have). As such I was only able to run hard to just a little shy of the 1000’ mark and then hit the brakes hard to keep from getting tossed off the track.
My 1/8th mile speed from last night was a little over 98 MPH but when I ran my 10.908 with the LS2 back in December my trap speed was 126.002 and with my buddy’s car (which has the same converter and gears) it was 126.105 MPH.

That’s actually very true and you make a good point - Before deciding on either an SS4000 or the PT4000 Dave asked me to record my shift extensions at the track and made his recommendation based on those numbers.
Correct!
The PT was designed to be the best NA converter at the track and when used from a roll it is one pulling mother, but it likes the be geared correctly 3.42 up to 4.10.
The SS has a lower end drivabilty factor that some people seem to like and works with higher geared cars(2.73 - 3.42) it pulls great but will not have the shift extention as the design was to allow a shorter lockup extention point so nitrous could be added.
