Deciding on a first stall
 

Not a DD but not a drag queen either. Will be driving it alot more on the street vs track. At first I was pretty set on a SS3600 but after researching I really like the sound of the PT4000 because I wanted a stall that would be a beast up top as well as give a decent 60'. But im afraid of how loose its gonna be on the street. Like I said, its gonna be my first stalled car, so im a little in the dark what would be right for me. The stalls im considering are SS3600, SS4000, PT4000, and on a smaller scale SS3200.

Yank or vigilante 3200-3600

ya a cheap stall is going to suck on the street get a good one go about 3600 on a bolt on only car 3400 would probably be perfect. 4k is just too much for a street car in most situations with street tires .

when i do it it'll be either 3200-3400

PT4000 stalls a little lower behind a stock head and cam car, yank says its around 3600. SS will have better drivability than a PT due to the higher torque multiplication (STR). PT converters are more efficient on the top end however. take a look on youtube there is plenty of videos of PT converters showing drivability.

SS3200 seems to be a popular choice for the street, from everything I have read the others might be too much and hurt drivability, except maybe the SS3600.

Wow! The opinions over here are alot different than over at ls1 tech. Most over there say AT LEAST a 3600.

yank

that is because LS1tech is all about every last tenth at the track, same dipshits who put T-rex cams in a DD and then bitch, or a Victor intake on a stock cube engine and wonder why it drives like crap, but damn they get their dyno numbers

Its just nice to get different opinions. Awesome man. So what stall do you have?

theres no point to anything less than a 3600 on an ls1, unless its got boost

I had a Yank 3600, but then swapped back to the T56 and sold the car to mike :P

I agree with 3600, but on stocks heads and cam if you go higher than that and aren't doing it just for the ET gain at the track you are just pissing away fuel mileage for nothing gained on the street. I liked my 3600 at the track but IMO it made the car run flat 90% of the time on the street, especially on a nice windy hilly road.

What do you mean flat? Iv never heard this before.

Well until the stall locks it is similar to a slipping clutch. Flat may not be the word for it but the car will not drive the same way it does now. Higher the stall speed further into the RPM range it will act like that. Using a 4000+ stall on a stock cam that starts making power at a much lower RPM never made sense to me on a street car. If it was a car that was more track oriented then hell yeah crank up the stall speed to knock down the ET. Have decide which is more important to you, the extra .2-.4 at the track or manners on the street. It will all boil down to personal taste and what you as the driver can tolerate. I for one would not go more then 3600 unless you have plans for at least a cam upgrade. I think 3200 is the sweet spot for a stock engine, nice bump in performance without slogging along at low RPM

Well, definatly makes sense. Im definatly getting one but whick one idk yet. I need to find out where the shift extentions are for the stalls. I think the ideal way of choosing a stall is around 800rpms below peak torque from the info I gather. But no one seems to ever follow it lol. If you go by the 800rpm you actualy end up with a 3200 stall for a stock car with 3.23 gear

Im goin with the PT4000 and i daily drive my car. If you watch vids on youtube the driveability is fine. And with my set up and peak power thats the right stall for me as far as yank says.

i REALLY liked the way last Of A Breeds car woke up with an SS3200. drove the same as stock. and PULLED up top. now that stall will also flash a little higher with motor upgrades to a point. id say it all depends on like everyone else sed what you care about. id say ask people that have personally used different stalls or used That one your looking at. heel drive someones car with similar mods and a stall your interested in if your still that undecided.

Lol you did NOT just seriously say that....LMAO. That's like saying "see hon, gettin it in the ass doesn't hurt, the girl in the movie loves it"

In all seriousness, I would try to get some seat time in a car with that converter if you can, that would tell you a lot more than watching it in action.

I agree, if you want to go big find someone who has one and see how you like it

obv its not the same as driving it but u do get an idea rpm wise watching that vid and it def isnt "flat" driving around.

Ive driven ss3600 stalled cars and they def go good but personally i want more.

Like people said it all depends on what you want out of the car.

KEVIN LAST OF A BREED!!!! OFFER UP A TESTY DRIVE IN YOUR CARO!!!! DOUCHE!!!

I know my motor isnt a LSx motor and I have a lot more cubes but.. I also have a 4500 converter. I can tell you that drivability does change a bit from the little I have been able to drive mine. You can tell down low(below like 2500) the car has no sack(like batman said). You really need to get that converter speed up to get the TQ multiplication.

Honestly though the car didnt drive too bad, taking off from a stop wasnt that bad but for something daily driven or driven heavily in the summer, I would probably go with something like the SS3600.

Just my .02

What is your setup?

stall speed is half the equation, torque multiplication is the other half. you can take two converters both a 3600 stall, one with a 3.0 STR and the other with a 2.0 STR.

the drivability is going to be much better with the 3.0 due to the higher torque multiplication however its going to be less efficient at getting the power to the ground at higher rpms compared to the 2.0


and fwiw there isnt a converter yank advertises thats going to stall above 4000rpm behind a stock head/cam ls.

the PT converters advertised as head/cam converters, they will stall 400rpm lower behind a stock head/cam motor.
PT4000 = 3600
PT4400 = 4000

the PTs have a lower STR but are more efficient on the top end.

its important to match your gears/tiresize and converter together. i think alot of the reason people bitch about big converters is because they put 3600+ converters in cars with 2.73s, 3.23s and 3.42s, more load = more work.
if your going to run those gears go with an SS converter, youll need the extra torque multiplication your loosing with the stock gears.

it depends, there is more to it than just stall speed. fwiw the fastest bolt on only LS1s are running PT4400 and theyre well into the 11s.

if you know what your looking at you can get a pretty good idea of what to expect just from watching. rpm extension, flash, etc.

Thats good info right there. At first I was pretty much set on a ss3600 but I really wanted a converter that would pull like a sob up top as well. Thats why I was thingking PT4000. But the decision is tough cause its mostly a street car. I wanna be able to mess around with other cars stop light to stop light. From all the research Iv done iv learned you cant have the best of both worlds in a converter.

Never said the fastest ones weren't high stalls, makes perfect sense. but I be willing to bet they don't see a whole lot of street time. And yes you do have to match the whole drivetrain but I believe he said he had 3.42's and I am assuming stock 16 or 17 inch wheels. Like I said on a stock car the ss 3200-3600 is, IMO the best compromise, taking into account tire size, gearing, cam selection etc. But really the best bet is to find some to drive and see how you like it. And I stand firm on the you tube video opinion. You can throw out facts and RPM bands all day long but until you feel it you can't possibly get a true opinion. You can't feel the throttle response or the cars reaction through a video you can only guess.

So anyway long story short find some to drive and see what you like. You can plan it out on paper all day and have it be nothing like you expected

agree with both ^ either ss3600 or PT 4000 but deff should drive one first. tonys car a bolt on lt1 RIPS for just bolt ons and a stall and he has a SS3600 so it kind of is up to personal preference

yes but the LT pulls way better on the low end than a LS motor

yea that's true

I'd put in a SS3600 and 3.73 gears. Done.

LS1Queen- your freakin nut's. PT4000 in your 99.9% street car.
If you want that you should just buy the converter I have sitting here for $300. Multidisk 4200 stall. It's loose enough for ya.

What do you think about just keeping my 3.23 gear with ss3600?

Sorry, I have nothing useful to add (had a 4200 stall vigilante in my 68, much different animal though, and everything else has or will have 3 pedals) but I had to give props on that comparison lol.

For a faster car = 3.73's.

3.23's tells me you want mostly a street car but your still looking at drag race converters.

the 3.73's will make the car tighter on the street and 60' better at the track.

Well part of it is just the ignorance of not ever having a stalled auto. Other part is wanting something thats gonna pull like a sob on top, thats why I was thinkin bout the pt but yea I realise I cant have best of both worlds. Think ima take your advice on the ss3600 and throw some 3.73 in. Would like to take it up to ya for an install but its just to far to deal with that. A tune is def possible though. Thanks for the reply.
