well I decided the summer or project for the next couple weeks is to finally install the muncie! So whats the turbo 400 worth? I need another driveshaft (55.5") for the muncie so I figure Id toss the shaft and 400 yoke with the deal. tranny originally came out of a 66 impala SS the yoke has the 1350 ujoint. so I got the adapter joint to go from big to little. The tranny is a running driving tranny. I dont know anything else about it, I pulled it from a impala I parted out. Stuck it in the chevelle and it ran/shifted fine. converter is stock. thanks jim
