Small Hijack
Great thread, I am also rebuilding a 727 for My Hemi project.
So let me add to this thread, what are the feelings of a factory 3 pinion planet, Vs a HD factory 4 pinion planet?
I was told by HP trans builder specializing in 727 that he was building 727 with these planets and kept breaking them. He went back to 3 pinion and the problem went away. This was due to triangulation etc. And if upgrading go with the 5 pinion, or stay with the three...

I would love to hear 440Jim's thoughts on this..
