Thanks Tom. Beings you wrote a book on these, what are your thoughts on installing a Transgo TF-2 in an original '70 Hemi 727 with original internals? Does it need it with the original Hemi internal upgrades? I have never experienced an original hemi 727 so I don't know what to expect. Will it screw things up with the different hemi valve body calibration, 5.0 kickdown lever and governor differences?
