gas consumption...390???
What kind of mileage should I expect (in town and highway) out of my 390. It's a 76 with about 30,000 miles, it's got an automatic trans., 9" (not sure of ratio's)...also can anyone tell me what kind of trans. is in my truck.

gas consumption...390???
your probably going to get a bunch of responses wanting more info, but I have a 390 in a 76 250 camper special and i get about 8 hgwy and way less in traffic. you should expect about the same in that era truck, hell even my 86 bronco with 5.8l only got about 14 hgwy.

gas consumption...390???
Considering the FACT there are so many variables regarding fuel economy it would be hard to get a specific answer.
Things to consider:
1)Quality of Fuel
2)Additives
3)Tune & Efficiency of Engine
4)Altitude
5)Driving technique
6)Topography where you are driving
7)How much city/how much highway driving
8)Gear ration & size of tires
9)Weight on the vehicle
10)Tire inflation
11)Vehicle design (drag)
12)Clean air filter
Just to name a few.
I drive a 78 pickup well tuned 429 engine,at an altitude of 3400 ft above sea level,with normal weight on the truck with a canopy,tires inflated to spec,using premium fuel,2.75 rear,C6 Trans, With my foot on the pedal like there was a egg under it, in Canada in a city that the downtown is located in a valley.
I get 14 city & 18-19 hwy.
Does this help ?
