That Camaro had a 305ci V8 and RPMs would be 1755 at 70 MPH with a 26" tire and 3.08 rear. The V8 had enough torque to make it work but 1755 RPMs is kinda low. It seems to me that the Camaro would have had the same problem and couldn't use that 0.63 gear below 65 MPH. That's a guess of course since I have never driven a 3rd generation Camaro with a T5 and 0.63 OD.
If my truck had a V8 then I would have used the T5 with the 0.63 OD.

My T56 is basically a replacement 6 speed for the T5 transmission. A 93 transmission adapted to replace the weaker T5 since a lot of guys were running 350's and 383's in the 3rd gen F-bodies.
I was big into g-bodies for a while and I had an 86 Cutlass. A stock option for them was a 200-R4 with a 2.56 rear gear ratio and either 195 or 205 14 tires.
