I am using the t56 but the R or aftermarket gear ratio.
It is wider at the bottom and closer at the top.
I understand that there is a significant loss of power in 6th, but the only time I use it is on the highway at 70. It is quiet (relitive term) and efficicient.
I am using a small 346 cu in engine with high rev 7000.
It works very well.
On the track I seldom get out of 4th.
Seems to be the best of both worlds in one for me.
