However the richmond shifted very bad... it was not a good shifting transmission at all.
i am now building a CSX car. I went with the 3.54 rear gear (the car came that way) and a Tremmic TKO 600 RR version with a .82 overdrive. one thing I cant stand is a really annoying low RPM overdrive. I think the .82 Road Race version will be just right... any one else out there with this setup?

You will love the 0.82 overdrive. It feels just like another gear, no big gulps and a reasonable engine speed at highway speeds. If you use a 295 x 55 rear with a 3.54 your 2500 rpm highway speed will be about 68 mph. If you switch to a 295 x 65 tire your 2500 rpm highway speed will be about 74 mph.
If you used a T-56 box with a 2.66 first gear, your 2000 rpm highway speed in 6th gear with a 3.54 R&P would be about 71 mph — and it would shift nicer.
