Ant, 3.08 gears with 1.1 final at 65 MPH is 2550 RPM. A friend has that trans and gear combo. His 427 is howling on the highway at 70 mph. He wears earplugs all the time. I personally would opt for a 5th gear OD. The TKO600 with 2.87 first is a great road race trans, and rugged also. With the power to weight ratio of our cars, I don't think that a 3.27 first gear is needed to launch the car. If your building strictly for the track it would be a different story.
