I would still be interested to know the performance stats of the TH400 used in these hi-po Pontiac cars...did they have the hd internals and hi-shift point governor like the Chevy applications..? 6 lug convertor?

The PQ trans I had in my 74 SD455 shifted at 5500. I would not twist a Pontiac up to 6000.
No need to.
