Alright so I'm having a lil trouble on deciding what size stall and what converter to go with for my 01 SS. All the posts that I've come across have people saying that they would need to know the mods of the vehicle before they can "really" help them. So I've put a list together of all my mods(I think). This IS my DD but I WILL be at the track every other weekend or so.

I understand I went with a big(er than reccomended) cam for a dd and I'm ok with that. Just wanna know what will perform better light to light, on the track, and in-between

Thanks

My bad. I put that in there bc that's what I was thinking about getting. Haven't purchased anything yet. But ya on the TSP site, they reccomens a stall of no less than 3800... But I've got a couple people telling me they wouldn't go any higher than 3000...idk what to do haha

4000 converter. I think that is a good all around size for motor.

If you're worried about DD and having too big of a stall, check out this video.

4000 Yank on a 2002 Z28.

I still want a few more opinions on what size. It but one more thing. What would the difference be in DD a smaller(3000) stall compared to a bigger(4000) stall?

Chevyboi09

After watching that video, I guess I can handle DD a 4000. Now, me being N/A, would the Yank SS series be good? Or is is there a more suitable converter for my set-up?

I have a MS3 with a SS3600, while it runs good I'd give up some of the tightness of this stall and go to a 4000 stall so it could run as it should....

3600 bare minimum. 4000+ recommended.

If staying NA I'd go PT 3800-4200

Chevyboi09

Yes sir I did. Preciate the info sepsis.

What did u mean give up some tightness c8r?

SS4000 would be fine naturally aspirated or the PT series as stated above.

Yank makes great general purpose converters, Circle-D and FTI will do more custom jobs so you could talk to them as well and get their input. Chris (Circle-D) and Greg (FTI) are both excellent guys to talk to and are really helpful. I wouldn't have an issue going with either of those or Yank if I didn't feel a custom built one would be better for me. I personally am opting for FTI because a speed shop kinda close by has a package deal, the converter, install, and dyno/street tune for $1350 and from what I've seen around here, unless you're doing it yourself you can't beat the price.

For reference, Yank SS series are $745, Yank PT are $795, Circle-D 245mm Pro Stage I is $775, and FTI runs $700 for their SRLS series.

To answer your tightness question real quick, in his application the 3600 is "tight" meaning with the gears and STR of the converter it is easier to get moving off idle at tame throttle. Going "looser" usually by getting a higher stall speed (although it is more complex than that) means that it takes a little more rpm to get the car to start pushing forward. A lot of things affect the tight/loose state of a converter: car weight, STR, stall speed, gears, and engine modifications, i.e. heads/cam

^ thanks for answering that. Spot on

You can't go wrong with Yank, Circle D, FTI and even PTC is good. I would call all of them.

I was going to go with a PTC myself but got a killer deal on my stall so I jumped on it.

Grr

PTC 10" race converter for the LS1. Ive had a bunch of different converters and you cant even come close to beating the PTC 10". Plus its only $425!

LS-ONE_DAY

No problem!

I've also heard great things about PTC, check them out too if you want OP. Grr, correct me if I'm wrong but I don't believe that that $425 is billet is it? I'm aware that billet isn't necessary for all applications, for normal daily use non-billet is quite acceptable, I just want to make sure the OP knows thats why the price would be different compared to the prices I quoted above which are all billet.

Kingc8r

iTrader: (21)

Yes that's correct. It's non billet, all companies offer a similar priced converter too

LS-ONE_DAY

I only mentioned the PTC being non-billet because he was considering a Yank SS which is billet, I didn't want him to think that the $425 converter was billet also, but yeah pretty much all high performance converter companies have more budget minded converters.

That cam is a top end cam that isn't very strong on the bottom. I had it in my car at one time. I wouldnt run a 3000 stall if it were given to me for free with this cam. 4k is what you want. I actually had my converter (PTC) loosened up to around a 4200-4300 and I could have even went looser and been fine. It was good for 1.55 60' in a 3500# race weight.
