A 351 Windsor (or 5.8 as they were known more recently) is a totally different engine than a 351M or 351C from back in the day........... or the 352 that was very similar to the 360 and 390. I am referring to trucks from the mid 80's up. Mid teens for mileage in a 351W/5.8 truck from that era is doable. I did have a '76 F250 with a 390 in it and it did get a solid 8mpg all day long. My current F250 also will get 8mpg...fully loaded, pulling 10,000lbs. I can average 10-11 empty...maybe 12 downhill.
I tried to figure out the 351 w/m/c. I decided that basically every f150 is a W except maybe the earlier ones. It’s hard to find any designation beyond 351 for a particular vehicle. To make matters worse, it seems that this is a common tinkering engine and can be bought as crate engines with carbs. It was tough to find fuel injected info for the 351W.
