Re: Cam with stall speed question

By running a looser converter you will be able to launch the car in a higher RPM range therefore making better use of your performance cam. A stock torque converter will usually stall somewhere around 1000-1200 RPM whereas your converter will stall somewhere between 2200-2800 so you will be right in the power band where you belong.

Re: Cam with stall speed question

For the most part even a stock engine will respond favorably to a convertor up to about 3000 stall.Aside from some extra heat in the trans and loss of gas mileage there is really no downside to a 2500 stall convertor.

Re: Cam with stall speed question

There are 2 stock converters one low around the 1200 and another around 1800
If you want to lauch off with a lot of power you have one up more in the power range
the low ones are for daily drivers around town...that way the torque converter is not always slipping when you accelerate fro 30 mph to 35 mph.
I have a 2500 and a 308 diff for the occasional social day down the strip and a 1200 and 255 diff for daily driving
Even so the rear still lets go with the 1200 and the 255 diff nps..

My Spelling is not incorrect...it is creative
