It is actually a .7 OD. . That's why I wanted to go this route. Tremec is either .64 or .82. . I received mine a little over a year ago. Jamie called one day and said it was ready if I still wanted it. My car has 4.10's in it and is a dream to drive down the freeway now. 75 mph = 2500 rpm, and it has plenty of run out. The math shows 175 mph = 6000 rpm. I've had it to 135.
That's good to hear My cay has 4.10s as well. I will be putting mine in in the next few months.
