My co-worker has a 1997 z28 with 373 gears and a 290/307 advertised cam. 4l60e tranny. What size stall can he go with?

 

3600+

 

Comp 306 should be fine with something over 3200, preferrably 3600. Don't go cheap. Circle-D 245mm 3600 is a nice unit for the price, some will say Yank SS3600 or nothing...

 

I have a edgeracing 3200 and it is a great converter.

 

At least 8000

 

I would say yank, vig, or edge 3400+

 

I'm still trying to get my head around the entire stall concept. I know say a 3400 stall allows you to rev up to 3400 till it breaks lose the tires. I also know you can still drive the car without hitting 3400. So say with an auto with 3400 stall, how do you actually use the 3400 stall to your advantage? Is there a certain break set up that allows you to disengage till the 3400? How do you find out how much stall you need?

 

Thanks all we shouldn't be spraying more than a 150 shot. Did I forget that LOL!

What are some good places to call, besides Summit.

 

Imagine dropping the clutch in a stick car. If you go WOT it will "Flash" to 3400 before the clutch grabs and then you GO. Driving normal it will slip a little just like you do a clutch in a manual car. Brake stalling will not let it "flash" all the way to 3400 like stabbing it WOT from a stop will.

 

you usually buy them directly from the Manufacturer. Yank, and Circle D are sponsers here their sites are listed to the right. Edge is not a sponser but you can google their website.

 

i have an FTI 3200 in my lt1 Trans Am and i love it! Greg was great and their converters are beyond compare.

 

Maybe the dumbed down version is a stall is sort of like load variable gearing. At light throttle and therefore light load a quality one wont slip much, but get on the loud pedal and load goes up dramatically as does the slip and torque multiplication.

Frankly your friend should have sought advise much sooner. I would say go at least 3400 in a quality stall like Edge, Yank, Vig. I don't know much about a few of the other companies listed so I can't comment on those. Avoid companies like B&M and TCI
