I have the ati converter out of my s10 for sale. It is currently setup for 5600 stall speed and is a 9 in model. Was 1000 new. Just spent 360 over the winter for a complete check up. Everything was perfect inside. I want ti run more boost and it being a 9" isint suited for it. Need a 9.5" or 10". It would rock for a nitrous setup supercharger or turbo looking at 9.00 and 150- 160 mph limit. Its made for th spline unput. So fits th350 th 400 and pg with th splines.
