stall......good or bad from the roll???

No converter pulls on the topend like a PT series. I run the PT4400 and it was absolutley night and day difference over my SS4000. It will launch hard if you ever want it to (I know it's not a big concern of yours), but is still very streetable. It's a lock-up converter, so tune it right and it makes for a great daily driver as well. It's a little loose, but you get used to it real quick. This is my third converter and it will be my last. The performance is sick.

by the way, i don't understand how a pt4400 can be faster from a roll. i know the shift extensions will be better but if you don't start until you are going 50 or so then you will only have one shift.
If I might make a recommendation, performabuilt built me a 4000 stall, but w/ and STR rating of 1.69. That STR sucks for a track car, but my car from a 3rd roll was much faster than with my TCI SSF3500. My TCI cut me low 1.6 60's while this converter is like a high 1.7. But my mph went up a good 2mph, but with a higher E/T.
The lockup was better with the performabuilt unit than tci and I am sure they are a couple hundred cheaper than say a yank.
For my car I will be going to a Yank PT series unless Performabuilt wants to take a crack a rebuilding my converter. But I want to race my car and cut sub 1.5 60's. i just wanted to mention it, that one of those performabuilt stalls and a set of gears would be pretty stout on the highway. Of course the PT will rip too but it won't be as drivable and it will hit harder off the line.

Also, remember that a higher STR can make the car feel tighter around town. It's all about getting a proven combination. The PT4400 proves that.....high stall + high STR = hard hitter off the line and very, very fast from a roll!
Also, most stalls for ls1s are lockup. I have mine tuned to lockup in 4th gear only at under 70% or so throttle, so my highway driving is no different from the stock stall. Its in the PCM tune, mine was done with hp tuners by rhino79
