What rpm stall converter should use?

It's just not like that anymore.....that is.....as long as you spend the money for a GOOD converter. If I had a stock stroke 360, 3500 would be my minimum flash for a hot street car. If I was thinking of throwing some strip in too, I would jump that to 3800-4200. There are some off the shelf converters that will work, but you need to talk to a good converter company and find out. They need to know it's going to be street driven so they'll know to make it tight enough so it will not slip and produce a lot of excess heat.
That’s good thank you.
