stall......good or bad from the roll??? i have been debating this for a long time. right now i have full bolt ons, 3:23 rear, tr224, tsp 5.3L heads, etc. i am running a stock stall. i am not interested in a hard launch. i will only run nitto drag radials. i know the car would be faster with slicks, etc, but that is not what i want. i want a good street car. the fastest 60 foot time i want to run is 1.8, whether the stall can do much more or not. i am interested in doing highway pulls. i know, a manual will suite my needs better but i will end up staying with the auto. i am considering getting a stall but i want it more efficient than stock. for this to happen, i assume it will need to be fairly small with a small str. i have been considering a PT3500. from what i read, the PT stalls are the most efficient at higher speeds so that is the route i was going to go. the other thing to take into consideration is the shift extensions too. i don't really care how it runs at 150 mph. but i am more interested how it runs at 80 mph than how it gets off of the line. my other option was to get a stall that i can lock at full throttle. i just don't know anything about these. i don't want to hear go big or go home. i know from a highway pull it will be slower and since i won't launch really hard off the line anyways, a very large stall will be useless for me. any opinions would be great.

the mods i mentioned are already on the car. i did the work last fall. i don't mind if the stall has the cabability to launch hard. i am still on a 10 bolt and i don't plan on changing that anytime soon. plus, the nittos won't handle a really hard launch. they are all i want though with this being a street car. it isn't a daily driver so i don't mind the stall being a bit loose. i don't have a problem going with a custom 3600 or 3800 but i want to make sure it will be efficient at high speeds. i have been told the yanks are more efficient than the vigs, so i was thinking that route too. locking up a multi disk converter is an option too, i just don't know anything about it.

by the way, a while ago i contacted both vig and yank with these questions. yank recommended their pt 4000. i have a feeling this would be a great converter for my setup but if i could sacrafice a little from the launch and gain a little bit at higher rpms then that would be great. vig recommended their their 3200 at the largest, but were kind of pushing the 2800. i realize the vigs flash a bit higher but there is still quite a bit of difference from their opinions. thus, i needed personal advice.

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.

Actually if you are looking for a good highway converter, get something with a lower STR. The lower STR will multiply the torque over a broader range of your powerband. On a H/C car just get a 4000ish stall, don't mess with anything smaller.
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.

ss4000 here, and it absolutley suck *** from a roll. I have raced the same car the same day, and from a dig I got maybe 3 or 4 cars on him, from a roll he beat me everytime. WTF! Apparentally the high str rating kills top end? And my ss4000 has a 2.6 str rating. It owns house from a dig though.

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!

lol. I run a 3000 yank Thruster, with a high STR and 2.73s. MY car straight JUMPS from a roll. I personally feel a 3600 is too big for your cam, these big stall people tolerate having to really punch it to get moving at a decent rate which sucks and makes your car feel like a dog on the street unless your willin to roll out at 3k from lights at normal acceleration
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
