The T-5 overdrive lowers it to 1700 RPM at 65 MPH and quiets things down quite a bit. Even with dual quad Holley carbs I can punch it in 5th gear and the car moves out without a bog.

I have a 3550 Tremec in my 65 Fastback and from 4th to 5th, my rpms drop approx. 950 rpms,very similar to your set-up,great for cruising on the highway and gas mileage........
I'll never have a four speed in a street car again!!!!!!!!!!!!!!!!
