another 66 mustang owner. I had the 200 and the rotten 3 speed on the floor. I got a maverick bellhousing and a toploader 4 speed out of a V-8, swapped the rear end for 2.80 auto gears. While it lasted it got great mileage on the freeway, right around 30 at 65~70 MPH. It was another one of those low rider mustangs. It had the worn out rear springs so I lowered the front to match
Then I got the bright idea of putting in a V-8 to match my transmission, and all thoughts of mileage went out the window.
