Re: What kind of gas mileage do you get with your 67-72?

The 67 with all the bells and whistles plus a 327 and glide that I had in Texas in the 70's got probably ten on the road if that. It was the worst gas hog I have ever owned.

The 70 longbed with 4 speed and 3.73 gears with a 307, power pack heads, Z28 Cam. 300hp 327 intake and Holley spread bore got 16 on a road trip to Texas.

My 71 3/4 ton got about 14 on the road running back and forth to work going 23 miles each way every day. Far less on short runs to town and back.

77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
