I have a Chnace Racing Converter for a Powerglide. It is Powerglide Spline and comes with Transmission Specialities hardened shaft. This was just gone through by Marty Chance in October and comes with receipt showing such. This converter stalled at 5000rpm behind a SBC that went 11.90's in an all steel 1963 Nova. The trans had 1:76 gearsets.
Asking $450.00. The shipping weight is 32lbs coming from 67147 to calc the shipping cost. I may be at track in November on the saturdays they are open and could bring with me.
