I have a low HP Super Gas car with a TCI Powerglide and have been using the inexpensive hardened input shaft from TCI. The input shows a pretty good twist in the splines after 60-70 passes. I know that I can go to the Turbo shaft to help eliminate the problem, but don't know the cost of having Turbo splines installed in the converter. Also, I see that TCI offers a better shaft with the PG spline, and wondering if it might work for me. The material is Vasco 300X (or something?) and I see that other companies offer shafts made with 4340 material, and some are called "Hy-Tuff". Can anyone recommend the best input shaft that has the PG splines? Or do I need to bite the bullet and go with the Turbo shaft?
