T5 Five speed slant six 74 Dart Sport.

Yeah and especially since it doesn't have to be the heavy duty world class version, that means there's that many more to choose from. I got lucky though and mine ended up being a world class unit out of like a 95 5.0 rustang. They aren't hard to come by and even new they aren't terribly expensive.
I believe the Ford T5 has better ratio spread. The S10 was designed for a truck that might get a load now and then.
