Best I ever got on trips back and forth from San Antonio to Houston was 18mpg and that was getting passed by everybody. It has an unshrouded mechanical fan, which almost seems unnecessary. With these tires my speedo is off by 7%, when it shows 70, I'm doing 65. Compare the mileage of the I6 vs the 302 and there is more than a 10% difference in economy. I'll need to drop the tanks and switch them out for the 87 to 89 style with the low pressure fuel pumps.
I'll be taking lots of pictures of the whole process on this one. A new mag-style hubcap injected some much needed aesthetic appeal into the lineup, and the return of the short box Flareside brought some youthful excitement to the F-Series trucks of the day. The 351 would go on to F-Series superstardom for nearly two decades, but the 400 - which offered little in the way of extra capability - would last for just a few years. It has a great running injected 300 in it that will be up for grabs too if anyone's interested. Towing my model T I averaged 13 mpg going 70.
I did have to change the oil pan gasket once. I am particularly curious about the fuel mileage. The bread trucks that most of these engines came in weighed several tons, were as aerodynamic as a barn and ran 3 speed autos or 4 speeds with 4. As for the F-Series, not only is it still the best selling truck in America, the F-150 is now the best selling vehicle in the world. Gasoline has a rating of 116k btu's upper end and diesel has ~128k btu's per gallon, which is only 9.
My old carbureted 300-6 did better than my dads 96 300-6 in the mileage dept. I did find an '89 extended-cab model w. « « « 1977 » » » 1977 Ford F150 1977 was a year to remember. No personal information, consider blurring out your tags. One big battery will start it fine.
Apple Computer continues to revolutionize the rapidly changing world of personal computing and portable technology. We'll likely be aftercooling this one as well. The starter has it's own high capacity relay built in, the fenderwell mounted one won't handle the juice. Sorry for the long post, but I would really appreciate good info about this. I'll also be learning quite a bit about what engine electrical stuff a '94 F-250 does and does not need for the gauges to work right with a diesel that only needs one wire to run. Might go as far as porting the head and camming it too. Towing my model T I averaged 13 mpg going 70.
Bumped the mileage to 5. I would assume a 4bt or 6bt at a similar power level would need about the same, with an edge to the larger engine needing more, but not by much. Never did hand calculate the mileage but I don't think my old 79 F-150 4x4 ever got any more than 20 mpg. It's a bulletproof engine that was still running at 250k miles when I gave the truck away. I try to run the first generation dodge 5. I don't need something with a lot of power or off-the-line zip, but just something that will tow a small load decently, and get great mileage. So it sounds like it's quite fuel-efficient engine for a truck, right? It has a great running injected 300 in it that will be up for grabs too if anyone's interested.
Bought an electronic ignition conversion kit Mallory Unilite , put it in and got 7 to 8 mpg. I did have to change the oil pan gasket once. I am thinking about buying an Inline-6 F150, and wondered what you guys thought about them. I'll be taking lots of pictures of the whole process on this one. Its the same reason why the Inline diesel's can get much better mileage than the V blocks of equal displacement.
No idea of mileage - it was all 20 mph or less, around camp use. Lee Colbert my truck has a 400 in it, but is the 390 good? My old carbureted 300-6 did better than my dads 96 300-6 in the mileage dept. Mine generally gets around 10-12 mpg. I probably could have just cleaned the surfaces and stuffed it back in, but while I was there. Probably the most expensive part for the conversion is a power steering pump. I wish I could have found another set f those 8.
Bumped the mileage to 5. It was so mild and the final temp of 180 assuming correct is so mild it is a non-issue. We'll likely be aftercooling this one as well. Also with both tanks I averaged 55mph. It can be lowered, lifted ,or stock but as long as it's a truck we want to see it. Did the tune up plugs, wires, cap, rotor, points, condenser, air filter and changed the clutch.
The pic is the only halfway decent one I have of my '71 right now. I don't need something with a lot of power or off-the-line zip, but just something that will tow a small load decently, and get great mileage. I may upgrade to a Dana 80 for the rear. My '70 has a nice bed that I rarely put anything in with a toolbox up front. It can be lowered, lifted ,or stock but as long as it's a truck we want to see it. Normally I ran 84mph and averaged 15mpg running with only my tools, and my equipment which weighed about 500 pounds and was about level with the bed rails. No idea of mileage - it was all 20 mph or less, around camp use.
