Three on the tree options

I have a 903 in my 66 Valiant with a 225. I love it. No, it's not synchronized but I can throw it into 2nd going 5mph and its fine. And no, it doesn't have overdrive, but I have done 75mph for hours and the 225 just sings. Honestly having less gears to shift makes it very nice. I have a T5 behind a 302 in a Ford and I'm constantly shifting gears. I truly don't think the T5 is any different than the 903 on the highway. They both cruise nicely.
