Makes sense. I don't think is cam is really huge based on what I know.

But knowing you have Don's old motor the .64 OD should be just fine, I seem to remember that cam "cleaning up" around 1600-1700 rpm from the few times I was in the car, so you should be able to shift into 5th around 50-55 mph and it will be happy.
That's a pretty low rpm so yeah that should be okay.

I am sending it back to Keisler cuz they have to modify the tailshaft or some part that apparently only they should do. I asked them it is more work than just switching that plate around. This will also allow me to run the Pro 5.0 shifter base that I want to run now, which I cannot in the tranny's current form. It's pretty cheap actually and they are just gonna switch this tranny out for a new unmodified one from Tremec where they have not messed with it yet except for the 19.25" shifter location (currently it is 16" - so, a 3.25" difference).
