I've seen most of the links/sources-most lean toward the s 10 trans but I have a half dozen out of Mustangs plus the zf 6 speed vet box---wanted to see some feed back from anyone who did the swap----------seems like very good combo of ratios for an flathead (100+hp ) for street driving-no racing, etc----------I think that having a good combo of gears would liven up the flathead install rate----------

my concerns do include the fact that the flattie is front (water pump) mount and then with the trans mounted at rear of tailshaft housing-----------originals had midmounts-------
