Thread: Wich stall conv. is best for big blocks?

Tweet

All converters have a stall speed expressed in RPM. If they didn't, your car would die when it stops.

Now, my first question is why? Is the engine stock? If it is, using a higher stall speed will simply cause more slippage and more heat in your transmission. If you've modified your engine, then you may have a case for a higher stall speed.

Higher stall speeds in converters are to allow the transmission to slip until the engine revs up into its power band. If you engine is stock, you're already there. Also, stall speed isn't just dependent on the converter. A converter will have different stall speeds on different engines, depending on the torque output.

I'm confused with your statement that all the converters you've found say "don't use on big blocks." Everyone who makes an aftermarket converter makes one for big blocks. For example.
