Thread: What stall should I get

Tweet

Hello there, I'm mud draging a full size chevy 3/4 4x4 pickup, 4:10 gears with 35 inch tires. I have a 454 bored .030 over with a xe268 cam, 781 casting heads with regular size valves and rocker ratio. Have a RPM airgap intake with a 750hp double pumper. Around 10.25-1 compression ratio. 350 tranny. Right now I think I have around 2500 stall it was my brothers old one. I race it in 4-low. But I can only hold it on line around 1300 rpm. Would it hurt me to maybe get about a 3500 stall. So I could at least hold rpm around 2500.
I was thinking a B&M holeshot 3600.

Stall-speed numbers are listed primarily to rate a converter’s performance level. Typically, the number assigned (2,000, 2,500, 3,000) will let you know the ballpark stall-speed rpm to expect from the converter. If a 2,500-stall converter is selected, matched with the PROPER COMPONENTS you should be able to foot brake stall the converter up to about 2,500 rpm. Lighter cars weighing 2,800 pounds and under will typically stall a little lower than the above-mentioned numbers, therefore you should choose a converter with a higher stall number for optimum performance.
adding another 1000 rpm's to your stall # will not nessacarily mean that it will give you another 1000. it will give you more but it will react to the trucks, overall build, gear ratio, tire size, weight, engine components, etc,etc,etc,

Call B&M . . . Not being a smartass - just thinking that the horse's mouth may be a good source of info.

you need to call a good trans converter company like Coan or others that know what your doing .running it in low lock makes the trans stall different and it has to be a good stall or it will not last long so bm is not hi on the good list less they did some things better in the last 15 years

I would try ATI,TCI,or Coan.
I have run all these converters of the years with good luck.
