The 460 cubic inch Ford engine was used in a variety of vehicles manufactured by Ford Motor Company from 1968 to 1996. This "big block" engine was highly valued for its high horsepower and abundant amounts of low-end torque. Today, the 460 Ford is available as a performance-oriented "crate" engine for high-horsepower racing and street applications. A motor this large has a big thirst for fuel, and today's gas prices demand ways of getting better fuel mileage out of it. With these tips, you can gain several miles per gallon and lessen the hurt this large engine can put on your wallet.

Skill level:


  1. 1

    Refrain from aggressive driving. Abrupt starts, hard stops and harsh, inconsistent throttle usage can not only add wear and tear to your vehicle, but it can also send the 460 Ford's fuel economy plummeting downward. Practice smooth acceleration, gentle braking and consistent throttle application.

  2. 2

    Tune-up your 460 Ford when needed. The average tune-up involves replacing spark plugs, filters and changing the engine oil. Performing these tasks can help improve your fuel mileage by 4 per cent, according to the U.S. Department of Energy.

  3. 3

    Remove excess weight whenever possible. A thirsty engine such as the 460 only gets thirstier when hauling excess loads. If you have heavy objects that you don't need to haul around, get rid of them. Lightening the vehicle will have a positive effect on fuel mileage.

  4. 4

    Keep the carburettor adjusted to the proper specifications. The 460 Ford engine uses a carburettor to deliver fuel to the engine, and a maladjusted carburettor can dump excess amounts of fuel into the engine and create excess emissions.

  5. 5

    Turn the engine off when at a standstill for long periods. Your engine nets 0mpg when idling, making the activity a waste of fuel unless the engine is being warmed up in cold weather.

  6. 6

    Obey the speed limit. These vehicles tend to get their best mileage when travelling at 55 to 65mph on the highway. Going over the limit will cause the engine to burn more fuel.

  7. 7

    Make shorter, fewer trips. Long trips and multiple stops burn fuel, so consider consolidating those stops and map out shorter routes to your destinations.

Tips and warnings

  • If maintaining an engine as large as the 460 Ford isn't in your budget, consider purchasing a smaller, more fuel-efficient vehicle, either as a replacement or as a supplemental vehicle for the vast majority of your trips.
