Alright, so I had made up my mind that I wanted a Yank SS3600, but then I keep reading threads that keep saying they regretted not going bigger... So, it has made me think about what I want to do.

I've decided I want a Yank SS3600 or Yank SS4000, nothing bigger. What I want to know, why go bigger? Does anyone have any proof to back up gains or losses from a bigger or smaller converter? My current mods are in my sig and in the future I plan on going with a cam with high .500 lift or low .600 lift on a 112 LSA most likely and a set of 2.5 LS6 heads. What converter would work better with that size of cam? The car is a nice day/weekend warrior, that I want to be fast. Goal is mid 11's.

So, LS1Tech, shine your light on these 2 converters? Benefits, disadvantages, advantages, etc.

im going with the 3600 its a great all around converter for the street and track if the car was a weekend bruiser with a decent amount of track time i'd go with the 4000

I run a SS4000 with my setup and do about 2-4k miles of regular street driving and have no problems.

i want to say 3600 for the street and 4k for the track,,, buttt,,, mannn,, in about 2-3 months your going to wish you had the 4k...

It wont be a big difference on the street.. And if you want a high stall convertor thats better on the street call fti. I know theres different style blades or something like that he makes.

and depending on traction the 4000 will have a better 60 and mph.

With you future mods in mind I would go with the 4000. I went 3800 with my h/c/i setup when I went to an auto since that what the trans guys recommended. I only drove the car about 20 yards and decided to get a 383 built for it. My cam is a 242/246, .621 lift and I am now going to a 4400.

3600 sounds like the ticket.

So, from the way it sounds, as little as the car gets taken to the track, a 3600 would be better, but then again, the car rarely ever gets driven anyways so I guess if I wanted the best performance when it does get driven I should go 4000? How much is mileage sacrificed going from a 3600 to a 4000? I still want the car to be very streetable since when I do drive it, it's usually an hour + one way to my girlfriends house and during the summer she enjoys taking it when we go places, so I don't want something that would be obnoxious driving around town either...

The way its gonna drive is going to depend more on how it gets tuned once you add cam and heads.The difference between the two converters under normal driving is negliable,untill you floor it.You will get totally used to it after a week or so,thats why everyone says i should of gone bigger. The car on Yank's website is my sons car and he had a SS3600 in for a very short time, and now has a SS4000.

So, sounds like I should probably go for the 4000 unless someone can persuade me to go with the 3600 instead...

dude just get the 4000, its gonna be a lock up convertor anyways so half the time its not even slipping. I bet in a year it'll be taken out to go looser

I just put my ss3600 in, it does not drive stock, but its not bad. Now I'm wondering how a 4000 would be. I'd probably go 4000 if buying new.

Thing is, I have never driven or ridden in a car with a converter. I've just read threads on how it's the "best" mod that can be done to an auto and how everyone loves their converters.

See that's how mine was really. Years ago I had a stupid loose B&M converter in a th350. The yank is a night and day difference. On level ground rolls real good at 2200-2500 rpm, aggressive accel is ~3000. I've driven it maybe 6 times since install(today) and I'm already used to it

I just went from a 3200 stall to a Circle D 5C 4000-4200 stall. The drivability is the same.. Go with the 4k.

I was skeptical to go from that big of a stall and think i was gonna regret it.. I dont regret it one bit. I am telling you, go 4k.

4k and I bet you will run 11 flat with your future mods.

I went with ss3600 and love it. I put it in last march and put about 10k miles on it so far. Maybe 20-25 track passes. Yank said it is the best street/strip converter and its 96% efficient.
I do wonder how much more I would have enjoyed the performance of a ss4000 but seeing how I drive the car so much on the street I think its the perfect choice. If it was a mostly track car then it would be ss4000 no doubt.
I gained .6 in the 1/4, .3 in the 60' and heres the eyebrow raiser...I gained 2mph which even my tuner (slowhawk) said I would most likley lose a couple. Im very happy with it.
I just did my first two 11sec passes minor bolt ons and a little weight reduction. Very nice converter.

I thought the rule of thumb for best launches was look at your torque curve to see what RPM you reach 80% on the upward approach. The idea being you would cross the torque peak with each shift. Anything below that is just a compromise for road comfort, which is fine if that's part of your goals.

3600 For all around driving and i cut a 1.61 60ft on Nitto 555R's w/ bolt-on's and ran 11.80@114 !!!

I cut a best of 1.55 60 ft with an Edge 3600 but on the street no traction whatsoever. I think your best bet is to talk with whomever you choose for your converter and have them recommend something.
