this guy is right.. thats what i ran when i DD my car.

but like others have said.. you need to figure out what your goals are for the car..

plan on DD it?
poweradders?
motor?
cam?
heads?
tires?

this all changes the factor on what converter would be best for your car.

full bolt on geared DD car get a ss3600
plan on a cam and DD get a ss4000
plan on full bolton car that you drive on the weekend only and running NA. pt4000
plan on cam or cam and heads weekend car NA get a pt4400


my car with full boltons gears and 315bfg drags ive got the pt4400 and i love it..

 

Thats what I run, but its a DD rain, snow, whatever.

 

Check Circle D out, I daily drive my 4C with bolt on's and 373's drives like a champ!

 

vig 3600 here yet to be installed

 

i see alot of guys with the high stalls, my question is why did you chose such a high stall? and how sluggish does the car feel off the line? i use to keeping my stalls around 3200 or so for daily driver but my LS1 GTO is the first LS car i've owned and after looking at my dyno i see the curves are totally different than anything i ever messed with. so do the higher stalls work better with the LS motors also?

 

What change was there in your MPH?

 

Ironically I just talked to Yank converters about two hours ago. I was looking at the ss3600. I'm going to run headers, ls6 intake, tsp 228 cam, patriot stage 2 heads, and 3.73's. I told them I was getting the transmission freshened up in two weeks and would be driving stock for a couple of months (I'll have to do some side work to pay for my future need for speed). They reccomended the ss4000. They also reccomended a retune for shift points, max rpm, and a tranny cooler. Yank said several customers run this converter with 3.23's like I will be doing during the summer before my listed winter changes. I took their advice and ordered it one hour later. Hopefully this helps on your decision, I don't think anyone's advice here is wrong. It just boils down to your goals and money, the hard part for most.

 

ss4000 is an awsome converter, good choice. Tires and tune are a must tho.

 

In a nutshell, yes. LS1's work very well with higher stall speeds. I started with a Yank ST3500 and liked it, but I knew it could be better. I upgraded to a SS4000 and loved it with 3.23's for a daily driver bolt-on car. Once I got the cam, I wanted all I could get so I upgraded once more to the PT4400 and unless I decide to spray the car, this will be my last converter. Smaller converters have a place as well and many run them happily and with great success. It all depends on your plans for the car. Me personally, I subscribe to the "bigger is better" club and I love it !

 

I started with the Vig3600 ,(not great for nitrous)then switched to the SS4000 (Yank)(very good w/nitrous) and finally i have the PT4000 (yank)(stopped spraying car). W/ a torque peak at 4400 ,LS1 engines like a little more stall than some hot rodders are used to.

 

i've picked up a Vig 3200 for the car and i'll go from there, if this doesn't seem like enough stall after the cam swap then i will go from there with dyno graph. but for a DD i think 3200 will work fine but as stated and from what i see the LS1 looks like it likes the higher stalls.

 

i bought an edge 3200....great so far.

 

I talked to someone on the phone at yank on friday about ordering the PT4000 but with just bolt on's he recommended the SS3600 due to the shift extension on the PT4000. But i plan on doing a cam swap later this year. Everyone i have talked to with a stall said go big the first time and not have to worry about getting a bigger stall. Due you think I should just go ahead with the PT4000?

 

If you're doing the cam swap for sure, then get the PT now and you'll be set when you put the cam in. It'll still be a fun converter, but like Yank said the shift extension is a bit much for a stock internal car.

 

What about the SS4000, how is the shift extension on it?

 

the ss4000 should have shift extensions right above 5000 rpms if the cars are set up similar.

 

basically you want anywhere from 800-1200 drop in shift extension..with my pt4400 im gettin about 900-1000, i love it...

 

Yank PT4000, and if you plan on spraying in the future get their SS version.

 

I think I'm going to go with a yank ss4000

 

Good info and feed back in here
