4000RPM stall? Can someone please explain to me why alot of you guys are going with 4000 rpm stalls in your cars? Just about every cam designed for the street for our cars shows a max of between 3100-3400. 4000 stalls to me just sound like there is now way that the car can be streetable. Is it bcause our cars have no low end torque and you have to get that high of an rpm just to get into the power band? The two cams I am looking at from CompCams are the 54-426-11 and 54-416-11 and both say the highest recommended stall is 3100. I am also look at Texas Speed and Performance 228R. They recommend a 3200 stall. What gives here?
do you have gears in your car? If not you will need a bigger stall to get things really moving with a cam.
I run a 3800 stall in my car and I think it is to small for my Tsunami cam. So when it comes out I am going probably around 4400 stall.
But, to answer your questions. People do run bigger stalls to get into the power band instantly.

What is wrong with just cruising with the 4k stall... I had no problems or anything goofy goin on. Gas mileage isn't that bad, but then again I didn't buy the car to worry about gas...
Anyway my motto on stalls is go big or go home!

I'm talking about from a stop, give it a little gas keeping it below 2k rpms. It just takes forever to get to 30 mph. Thats all, I love the stall and wouldn't go any smaller. And I agree, gas mileage isn't to bad either, but I don't care what kinda mileage I'm getting. It means nothing to me when I'm having fun.

In my book if the converter locks up its a street converter, thus streetable.
You certainly want to match one to the combo, but some of the fastest stock internal guys run 4000+stalls cause they wanna run a number.
I'm running a 4000 stall and its not nearly loose enough for me. Strator design will affect streetability almost more than stall speed. If your gonna stay NA and throw a cam in it, don't look at anything under 3500 imo, maybe a tad smaller if you got 2.73's. FI is another story.
Just pick a good brand and don't skimp, and get a decent cooler. If its mostly a steet car and your afraid to go big I'd recommend a Yank SS3600. You'll end up wanting to go bigger later anyways

How "streetable" a converter is depends more on the gear selection as well as the STR.. 273 gears with a 2.4 STR is not going to be very street friendly, in most peoples eyes at least.
I drove a VIG 4400 and 323s for almost 6 months with no complaints. Some people would consider a drag car. It is all the eyes of the beholder.
When TSP recommends a 3100 converter for their 228 cam, that is the minimum. I have a 226/228 .588 114 cam and have a PTC 4000. It hits hard (1.50 short times) and is still a full weight car and spinning ever so slightly out of the hole..
Ls1s absolutely LOVE big converters.. Even small cam cars. The quickest ET on average I see with a 3200-3600 converter is low 1.6-1.7 short times.. The average for 4000s are 1.5s or quicker. With ALL sorts of varying cam selections.
The difference between say a 3200 and a 4000 (granted both quality converters) driving around town is going to be around 150-200 RPMs differece, with the same gears and weights of cars. At WOT there will be a HUGE difference as well as after shifts (how much it drops after the shift).
Hope that cleared some stuff up....

the reason i went with the 4k, b/c i originally was hellbent on the 3600, was that the guy from yank said my times would be much better in the 1/8th without much rpm difference with the 4k. he said that if i ran the 1/4 then the 3600 wouldve been a better choice. it really depends on the circumstances. those guys definitely know what they are doing. you should call em
I love my 4k stall, and 3.73s. I can mash the gas any time i want, and its gone!! Daily driving it wasnt an issue at all really either, but then again ive never been in a stock stalled auto LS1.
I have a stock cam in my car and run a 3600 Vig. I've had many.. many people claim I have too much stall but funny they all tend to quiet down they see me crack 1.5 60' times and bottom 12's. When my car shifts at WOT It never drops below 4600-4800 rpm. I have a couple vids on my fquick page. i've been running this same stall since 2007.. almost 60K on the converter!

I've had 3.73's and a SS4000 with a stock internal motor for a little over a week now and it's fun to drive. I DD the car last week and it drives the same on the highway as it did before the stall, until you decide to get into the throttle. It will take a little more gas than you are used to when trying to keep up with traffic while leaving stop lights, but after a week of driving it that is starting to become normal. I wouldn't be afraid to get a big stall, especially if you are going with a decent size cam that will take advantage of the big stall.
