Question

anybody knows the fuel mileage on a 1975 chevy pickup with a 350 motor and a rochester qudrajet 4bbl carb the pickup is 2 wheel drive with a th350 3 speed automatic transmission the gross weight is 6400

Answer 1

My '77 Jimmy 350/4bbl would get 9-12 consistently.

Answer 2

Well I know my 82 F250 w the 351 was around 9MPG or so. It all depends on how efficent its running. If the motor is old and wasnt taken care of. But if its like a new crate motor its going to be higher. Best way to find out is fill your tank, go for a ride, fill your tank up and do the math between the gallons & miles and you will know.
