As long as it's the "short shaft" 350, with the 6" extention housing, the lenth will be alright. If the converter has the "small" pattern, it will bolt to your flexplate; if not, redrill it. You'll also need the fine spline TH 350 slip yoke. You can also make your stock column shifter work, and the Nova vendors may even have the shift indicator glass/plastic replacement. Now, your Powerglide should be air cooled. If you still have the COMPLETE turbine/converter cover, and the converter with the cooling cover on it, I'd be interested in those; P.M. me and we'll talk about it. The other thing is, your Powerglide is most likely air cooled, you'll need an aftermarket external type cooler for the TH 350 trans.
