I have a 2002 ws6 ta 3.23 gear car. I would like to know which stall between the yank ss3200 and ss3600, would be best for my future combo of mods. My mods will be tsp 1 3/4 lt headers, tsp. 3in.ory, slp lid, ported stock tb, ls6 intake, tsp 3in catback, the ws6 store high lift hot cam 218 227 600 112+2, tsp stg.1cnc ported ls6 heads stock valves 62cc 225cc runners. Car is weekend warrior with mostly street driving and at 1/4 track maybe few times a year. Would like to run at least a low 12 or high 11 with good driveability.
so...the most run of the mill LS1 mod list ever...with one of the most common converters for these cars ever
there's 100 threads just like this...go with the 3600 if you are dead set on picking one of those two
Otherwise, there's not reason NOT to step up to a 4k stall. They drive fine, cruise the highway fine because lockup, and the performance is better
Also check out other supporters of this forum like FTI and Jake's Performance. They build great converters also
Ok. I just didn't know which one because the ws6 store cam isn't that big. I wanted to make sure the 3600 wasn't too big for my cam. Can you tell me about where this cam will kick in and the power curve I'll have with this combo. Thks alot
My first setup with a ss3600 was with stock internals, 3.23, boltons, drs and some weight reduction. Drove perfect. Got that setup at a best of 11.9@112 with a 1.6 60'. If I was to do it again I would of went with a ss4000.
The SS3600 isn't too 'big' for LS1 stock engine/stock cam so it wouldn't be too big for what you listed.
Agree with post #2 and #4, go with SS4000.
Everyone's afraid to go 'big' stall like SS3600/SS4000. A SS3200 would be disappointing to you and leaving a lot on the table.
I'll tell you this........ I had a yank 3600 to start off. It drove perfect. I destroyed the trans and converter was damaged as a result so I sent it back and had it rebuilt. I decided I wanted to try and go down on stall to get better fuel mileage....not only did the fuel mileage not change, I lost (gained) .2 in the 1/4. So with the 3600 I went 1.7 60ft and the 3200 I went 1.9
I took the converter back out and sent it back off and had it readjusted to a 3600.......If that tells you anything...
I've got the SS3600 in my near stock 01 and there is no drivability issue. You know it's there but you get used to it very quickly and hardly notice it in normal driving. Huge difference when you hit it.
I can't imagine going smaller. In a do over I would seriously consider the 4000.
Applying a SS3200, SS3600, and SS4000 as 'flash to' on a typical stock LT/LS dyno horsepower graph, the SS3600 would flash to a 25 higher horsepower point than the SS3200 does and a SS4000 would flash to a 20 higher horsepower point than the SS3600 does. It's always better to immediately jump to/flash to a higher horsepower point in the powerband.
Nice work Denny! I have a 4000 in mine but as we know, what's best for NA isn't always what is best for being on a big shot of N2O and it's not like I'm running on the bottle 100% of the time on the street.
The SS3600 isn't too 'big' for LS:nod1 stock engine/stock cam so it wouldn't be too big for what you listed.
I would consider a ~3500 stall speed to be pretty much the minimum for performance, even for a totally stock LS1 and especially with 3.23s or numerically higher gears (any high quality converter should still feel reasonably tight at this stall speed, really even with 2.73s unless you're particularly bothered by looseness). With a typical mild to moderate build, something in the 4000-4400 range is probably going to be ideal depending on the overall setup, so the 3600 is definitely not too big.
Referring back tp post #10, yes power adders and very high horsepower NA require a different classification/type to keep all that power from 'blowing thru' the convertor and not being applied to the driveline. A 'cheap' convertor will do that even on a stock engine, a good desired 'flash to' rpm and then everything above that is too much 'slippage'. To put that in a 1/4 mile strip situation, that 'cheap' convertor would improve 60' ET and overall ET slightly but result in equal or slightly less top end MPH because the horsepower at the top end was just 'slipping' thru.
I have personal experience with both so here's my unbiased opinion. If the car was a daily driver then I'd opt for the SS3200 as I like it more than the SS3600 for that purpose but only for that purpose. For all other purposes, SS3600 hands down (between the two). The SS3600 is a great converter but after about a year I stepped up to a PT4000 which really kicks the **** out of both of them from a roll and at the track. It's not for everyone though, I think the SS3600 is a happy medium for a lot of people.
If you've never owned or driven a stalled car before I'd see if you could find someone local with one to see what feels right to you. Like exhaust systems, everyone has their own opinion and tolerances so first hand experience is more valuable.

I have offered AND given rides for/to locals. They were always afraid of going too big. They considered 2500-3000 as big, HA. Rides given with the SS3600 with sometimes the 3.23s' and sometimes with the 4.56s'. And the rides I've given also included letting them drive in city traffic. Don't know of anyone that was still thinking that 2500-3000 was big. The street friendliness of the Yank SS3600 was always excellent for them.
I was in the same situation a few years back. I was torn between the ss3600/ss4000. Well I decided to go with the 3600 and was very happy with it! I’m a Bolton/3:23 t/a. Well long story short I’m running a ss4000 now. Like everyone says don’t be afraid to go big. I would’ve saved myself money on the re stall and time on my back pulling the trans twice. I didn’t see any trans temp difference and drivability was pretty much the same until you floor it. The 400 rpm difference is really noticeable if you know your car. If anything mpg in stop and go traffic may have slightly lowered.
