What is the best engine for an F-250 2 wd that will be used for only occasional heavy loads?

I want an F-250, somewhere between 68-79 and hope to put a slide-in dump bed on it, for gravel, barkdust etc.

I want something that gets better mileage than the 4.9L 6 cyl that's in my 83 F-150 (10 mpg city) and hauls a bigger payload.

I don't like the 80's Fords that much, so I'm looking for either 68-79, or 99 and up.

I'll drive it, when not using my V-10 (8 mpg city) van.

Having to pull the dash to replace instrument lights really passes me of, in my '83. I'd rather switch, than fight.

 

My '71 F-100 has a 351W. It's a really easy swap - same bellhousing pattern, perches, and motor mounts as a 302. The longer stroke helps torque and mileage isn't terrible.

 

How terrible?

 

Hmmm... if ya don't like 10 mpg get a 2004 or newer Powerstroke but a 300 in a Bump or Dent F250 is decent but a slide-in dump will tax it even more being that it is carried onboard more often than not.

Your current 300 should get more than 10 MPG. Check your driving style.

 

...or your tune

 

I haven't driven it for a few years but it seems like 13 or so MPG.

 

F-250 with a dump body isn't gonna get better than about 12. Get a 7.3 or 6.0 super duty if you want better than that.
