why do you want a lower stall? they do come in 3500. they may even go lower, i am not 100% sure.
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.

It's the way Yank designed the PT series. They are the fastest, baddest NA converter you can get IMO. Yes, shift extension helps.....but the PT series are extremely efficient and that plays a part as well.
On my car, punching it from 50 MPH will drop it into the meat of 2nd gear. It'll then shift into 3rd at ~75ish and the RPM's only drop to ~5800. 3rd will carry to ~145ish....but the pull never slows down like it did with the SS4000. Obviously my setup has a lot to do with that, but my car pulls better from 120 and up than it does below that.

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

yeah i have been told that the vigs and the yank ss converters suck from a roll. i can't have that. i rather stay with the stock stall if it will be faster from a roll of 40mph or so. i have a feeling the pt converters will be better but i don't know by how much. its like will they be worse than stock from a roll???? i don't want to lower the str too much. i think the factory str is around 1.9 if i remember correctly. i don't wnat to be worse than stock anywhere in the power range from idle to the rev limit. maybe i am asking too much...

I have the exact combo as you with a performabuilt 3600 converter with the 1.6 STR and its got me a 1.64 60 on nittos. When I had the stock stall with the H/C I got a best of 12.52 with a 1.87 sixty foot. With the converter I droped down to 11.8 with a 1.64 sixty foot.

directly from vigs website, this scares me:
"Some car enthusiasts put all kinds of money in the engine, transmission, torque converter, NOS, rear end gears, etc. then want to cripple the torque converter by lowering the STR to try and prevent wheel spin on take off. This is as foolish as pulling off one of the plug wires. "

Any good converter is going to give you a substantial boost in performance over a stock one. You won't be worse off at all.

To caveat on 99hawk262's statements on Yank PTseries converter ...
These videos speak louder than words.

I've driven 99hawk262's car before and honestly it feels like my car cruising around town. FYI, I have his old Yank ST 3500 converter.

I have the ss3600 and have raced from a roll several times. From my experience the sweet spot is around 50-60mph. It really pulls hard when cruising and then around 60mph downshifting into 3rd and punching it from there and then shift into 4th manually. I love mine

The bigger the stall, the slower you'll be on the top end. All things equal the manual cars will always have a higher trap speed, and its gonna be even more evident on the street. IMO, a 4k stall is great at the track but useless on the street. Try to lauch a 4k stall on the street will only end-up frying the tires even with drag radials since the street is not a prepped racing surface. If you like racing from a roll then keep the stall speed low.

a 1.8 60-ft time is all i want to do. i have a stock 10 bolt and i have a street car with nittos. i want to be able to enjoy the car. if i wanted a drag car i would build one.

If you don't wanna go too radical a tight 3500ish stall should be fine, maybe Yank ss3600. I have a TCI SSF3500 I can sell you if interested about 2.5 STR, but it's not best from a roll. Honestly my current stall feels a little tighter than the TCI did and it's a 4000, that is why I have to get rid of it. The stock stall is about 1800 rpm w/ a 1.69 STR. My 4000 stall will kill it from a roll simply because of the shift extension. I have only run nittos on my car through a 10 bolt, you would be surprised what you can do in an auto through a 10 bolt on 17" nittos.
