Dennis, my car has a Tremec T5Z transmission with a 2.95 first gear with the 5th or overdrive ratio at .63.

The third member is the center section of the rear end, the ring and pinion gearing, posi-traction assembly, etc. MY rear end gearing is now 4.11

My car is putting out 400 horsepower with 336 H.P at the rear wheels. The torque numbers are quite a bit higher.

As far as curb weight, haven't a clue. The fiberglas stereo surround in the trunk is adding quite a bit of weight.
