Ok I know this has been talked about before but I still don't quite understand it. Old age I guess. How does a stall convertor work and what is the difference between the stock and maybe 2200 to 3000.
Is the truck supposed to move at all before the rpm range or is it just that the power doesn't kick in. We put a 283 in my sons s-10 with a healthy cam. It seems very sluggish and was told we might need a higher stall. His is supposed to be 2500 or smaller i think. really need to understand the principles of the higher stalls.
Also even though the truck runs good it is very unresponsive throttle wise. Have a 650 edelbrock on it. It doesn 't want to idle even either. Sometimes it stays up around 2000 and then will finally come down to idle just setting there.
Thinking about switching mine to his truck and see what happens.
Thanks a bunch.

Got my new motor for the luv at the shop getting line bored and the deck planed and squared. Waiting to get my parts going for the rotating assembly. 350 bored 30 over. Looking for a good used victor jr intake or better for 2800 rpms and up

This is a good explanation of it too

Put your truck in gear and stand on the brake then floor the gas and what ever the RPM is is the stall the converter will do with your motor.But it is allot more technical then that this is just the short version.

Keep in mind that a converter is torque sensitive in that a 2500 stall for a 350 will be 1800-2000 on a 283 or 3000-3200+ on a 454 due to the torque of the respective motors.

Example; I have a factory corvette 350 1800 stall converter that i put behind a 70 cad 500 in. motor and it stalled at 2600.That same converter on your 283 would be a real turd plus it is a 12" and heavy. Also i have a 9" converter that i had behind a blown 350 that stalled a 5500 with 15"s of boost but on your 283 would probably be only 3000-3200 and is a lot lighter letting the motor spin up faster.

I hope this helps.

Thanks for the info and links
will see what i can come up with

Stall is the amount of slip built into your convertor. Unless you have a custom convertor built for your specific application, you can't really go by the 2500 stall, 3000 stall etc., because as TJ explained, it will stall different behind 2 different engines with different torque levels. The more torque, the more slip, the greater the stall speed.

Now for the 283 sluggishness. A 283 is a small displacement motor with relatively little torque. A healthy cam will not do much if it makes less torque. Anything over the 270/470 range is not good for those underpowered little darlings in a driver. A 283 will scream with a big cam, but it needs lots of compression and stick shift, IMO to help it get there.

A 600 Holley would probably help also...

SFPP!

Cool, will look at his speck card on the cam. Not mistaken but i think he has 10 -1 pistons. not sure of the heads he used.
I do know to that at 70 mph in overdrive he is running3500 rpm's. i think taller tires in the back is in order too.

Talk to the place you want to buy your converter from and tell them what you want it to do. That should help on the decision on which one to buy. We always get them from a place that builds ones for race cars. I don't know $$$$ vs one off the shelf.

Will have to check what he has, he bought a new 700r4 witht the stall in it and they said it is what he needed. Will see if I can find what it really is in it and go from there. I am almost sure it was supposed to be either 1800 to 2200 or 2500 period. I haven't drove it and just going by what he says. I do know it has some carb problems and I think maybe a vaccuum leak but not sure.

This is how I check the stall on my race truck. But you don't want to hold it there but for a split second. Otherwise bye-bye convertor. The convertor I have in my drag truck I got from http://www.autotransdesign.com/ Have had very good luck with it. Been in my truck for 3 years.

I guess what it boils down to is for the street you need a lower stall but more than stock on a street strip vehicle.

When i first built my truck i had a 283 with a 4sp and a light GM flywheel (14lbs.) It had a Isky 500 lift 300 dur. and was a lopey no bottom end motor but once it got past 4200 rpm it was a rocket all the way to the 8200 shift point. See where this is going?

Because of the lack of torque at lower rpm's i would look to getting a smaller converter like one out of a 2.8 S-10 that is built to fit your flexplate. This is much lighter and will stall higher ( 3000-3500)or less witch is about max for a street setup but will let the little 283 motor spin up in a hurry.Oh and that little 283 will probably want to run in the 3500-4000 rpm range just to start making power so a smaller cam will help the bottom end but they still are a buzzy motor and have to be driven different than a 350 would be.Don't give up on the 283 as they are a very tuff little motor and are fun to drive.Another point is you get a wild sounding motor that is easy on the gas budget to.

cool

when i ge my motor finished for my luv will have to throw out the specs and see what you all think for a converter

On a street car be careful not to get your stall in your cruise RPM.
