2700lbs is pretty light. What was the rear gear ratio?

I wonder what the 67 bird HT cars got for mpg with the OHC6 motors? Those car if I remember are pretty darn light like 3100lbs. I would guess in they were in the 20s but 36 mpg is darn impressive.

This was about all I could find from Wiki

The Feather Duster featured lightweight aluminum parts including the intake manifold, bumper brackets, hood and trunk bracing, and manual transmission housing, for a weight savings of about 187 lb (84.8 kg)—5% lighter than a standard Duster similarly equipped. It came with a 225 Slant Six with its distributor and single-barrel carburetor calibrated for economy, a low-restriction exhaust system, an extra-high rear axle ratio, and was offered with either the Torqueflite 3-speed automatic or A833 overdrive 4-speed manual transmission. It was the most fuel-efficient car in its size class, achieving up to 36 mpg highway and 24 in the city with the manual transmission option. (along with Dodge's version, the Dart Lite).

As a result, they were getting as much as 20 mpg in town and 36 mpg on the highway, numbers comparable to today's economy cars
