the converter flash at 4600rpm. it is very good, it's a 9 inch treemaster from ATI, it is tight for the street also. I may ask them to reconfigure it to arroung 3500rpm. I think it will be even more effecient at 3500rpm.

When I complete the work (arround june), I will will let you people know the result.

What does it stall to when you hold the brake and mash the gas? or do the rear tires just spin?
Sounds like you would be happier with your loose TC and a lockup torque converter. All the fun of a loose TC and the cruise rpm just like a manual trans in high gear(1:1).
No way I would go from 3.73 to 3.08 with that loose of a TC, your TC and trans inpout shaft would almost never run at the same speed. In other words it would always be stalling, or always"on the converter".. Temps will be higher for sure with the 3.08's. City economy would be worse with the 3.08's.

This is why I will probably changing both the gear and converter......otherwise like you say it will always be on the converter and just creating more heat.....

I think/hope there is still room to tighten the 9 inch ATI converter to stall at maybe arround 3500rpm on my car.
