lets say the STR is the same (2.0), is there a huge difference between a 3200 and 3600? And will this difference be huge at the 1/4 strip? or is it just .1 or .2 better? why does everybody want a bigger stall? going from 3200 to a 3600 does not seem that big of a difference to me. just by looking at the number.
400 more rpm. any help would be nice. thanks

It'll make a bigger difference then you think. Our cars make much better power at 5000 rpm's then they do at 3000. So in reality a 4400 stall is best suited for max potential. But many people don't want "loosness" of a 4400 stall and or they have plans for N20 in the future which may require the stalls with less stall speed and shorter shift extensions.

There is a famous saying around here that you should pick the stall size you want and then go one higher. That is soooo true. My buddy went with a 3000 and now he wants a 3500 like mine. I went 3500 and wish I had gone with a SS4000.

I can't stress enough that I think you should get the 3600. The bigger stall size and higher shift extension will not only make you quicker in the quarter mile by at least .1 but will also make you a little faster from a roll. It'll take you about a week to get used to it. Then the car will feel like stock again and you won't even know its there. That is until you punch it

Good luck.

u will see .3 tenths with a 3600 stall and be good for the street too. id go with that one. o that is assuming u will be on drag radials. street tires? no gain just lots of smoke

o and lets say u have stock street tires now and u put on some sticky drag radials(.3 gain) and a 3600 stall(.3 gain) ...that will put u up about .6 tenths faster than u are now. good combo here

the thing is i want the 3600 but dont want the higher STR. So i was thinking about staying with the 3200 and its lower STR from Yank.

Don't do the guessing game!! Call PTC, tell them what you have in the car and what you are planning to have done and let them build you a converter that suits your needs..

well i havnt done a stall yet however a mag article ls1 dos & dont says over a 3300 stall you need computer work because of slipping. i just cant decide on this mod. ??? i know it will be faster at the strip but how does it affect drivability and gas milage? good luck!

thats incorrect. I have a 3400 stall and its fine, no tuning for the stall its self. You need the lock-up clutch **** adjusted in the computer with a stall usually though.

I have a 3200 stall and wish i had a bigger one.

im in the same boat as you. after reading the article on yanks website i want the lowest STR i can get, but all the 4l60E stalls seem to have "poor" STR ratios.

in all the reality, the only thing thats "poor" is probably my understanding of whats goin on with the converter. when i get more serious about droppin the money im gonna shoot those guys an email and see what they come up with. im not lookin for anythign too fancy, just a stall to go with a dry nitrous kit. in the future when i do the 4l80 and the twins, ill get a custom stall at taht point. the key to success is gettin the right part the first time, even though it almost always costs more, its always worth it.

I have the Yank 4200 with a 2.7 STR and it's been untuned for over a year and I DD every day although once it's tuned I expect a nice drop in ET but for now I went from 8.6 to 7.9 with the stall and exhaust upgrades and thats coasting thru the 1/8 mile traps cause' the car will not shift at WOT on the 2-3 shift cause' it's not tuned but will shift under normal driving so it's not a DD issue!
