So how many rpms do you have to rev to get the car moving with that 4000?

 

A high stall like a 4000 doesn't take much rpm to get moving, they're designed to roll with very little throttle. It's when you get on the car that the stall will flash to 4000, or if climbing a incline it will require more throttle, the feeling is like towing a trailer. Don't be afraid of the new higher stalls with lock up clutchs, once the converter locks up it will be like stock.

I would recommend taking a ride in someone's car, I see it every month on the forum where someone buys a stall and wishes they wouldn't of been afraid to go higher.

 

running Yank 4000 also, I do not know at what RPM it begains to move I never pay any attition as to RPMS very happy with it, ran Yank 3500 for 8 years before going to 4000
ps: have a spare 4400 waiting on the side untill I find time to try it

did you run that 3500 with stock tranny and 10 bolt?

 

yep, stock trans lasted 68k then lost 3-4 clutch pack, rebuilt lasted 700 miles lost 3-4 pack again ( my fauilt hot laped/stall 30-40 time on street in 2-3 hours- yep running a 24k cooler, but no timp gauge) rebuild again then 2 nd slipping,rebuild with new builder/ with a lot of GOOD parts( 1 k IN PARTS) did vac mod, seems ok after 1000 miles, still on 10 bolt but have over 1 k in parts/ mos 31 spline axels/detroit locker/ta cover/3.73...have 9 in/locker/4.10 waiting to install
good luck

i went from a fuddle 3400 that seemed loose as hell and got me around 18 mpg to a vig 3200 and now i have damn near all of my stock stall mpg back, plus she still moves when i want. Im so much happier now

if you have to daily drive and have any amount of commute i would highly recommend the vig 3200, especially if you are on a stock cam.

 

im not really sure. 1500 maybe? just kinda a guess. pretty much starts moving almost as soon as you give it gas. when you smash on it is when you really know you made the right choice.

 

this may help

I daily drive my Cammed 4000 stall and LOVE it!! Even from a roll, it gets the job done. I just swapped out my cam, so i havent really driven to much since, but with my 234/230 it pulled great, and drove well even in town.

 

my ss3600 moves at a 850-900 rpm idle, unless I'm on a hill I can cruise around town at under 2200rpms stop and go...takes a good bit of throttle before the stall starts to raise considerably

 

go with a ss4000. i dd my car everyday with it and was perfect. like what was said before i wont have another fbody auto car that isnt stalled.

 

I have a 3600 stall with my new set up and for DD driving it's great.....I have not taken it ot the track yet. Still need a dyno tune and 3.73s.

 

At the end of the day you are going to most likely be stuck between a 3600 or 4000.

The number one thing is to go with a quality converter. Something with a billet front cover from a sponsor; FTI, Yank, Circle D to name a few. They can all help spec a converter for your car.

Also generally your going to need torev more with the bigger converter under light throttle. Every product is different but you can think of it roughly like this.

My converter with 2:73s needs just under 2k to move from a stoplight at the rate of traffic. A buddies car with a 4k needs more like 2.5k to do the same.

If you go with a bigger converter the STR ratio frequently gets higher. More heat for the tranny, so something to consider if your on the stock 60e like me.

 

I picked up a Yank SS3600 from someone one here.. i can't wait to get home and drive the car!
