I am looking at a 1976 F-100 with a 460 engine. I was just wondering what those of you who are running 460's are getting for mileage. It won't be a big factor on if I get the truck or not. I am just curious.
Thanks,
Terry
I get about 10-12 mpg out of my pure stock 460 (in my 79 f-150) That's with being on and off the gas (going from barely on the gas when i am not in a hurry, to smoking the tires off the line.
I just started driving it this spring, never thought i'd get that good of milage! Might even go up once i ditch the restrictive stock exhaust.
it really depends on a lot of things. it's hard to tell exactly what this engine should get. take ito account aryodynamics, if the engine is running to it's best, weather, driver ect

I get about 45 minutes between gas stations with my 1975 460!!
Seriously however, I'm running about 8-11 MPG on a freshly overhauled
top end. I put in a "Comp Cam" Dual Energy RV cam and a Holley 600 CFM (vac secondaries)on a stock intake, heads and exhaust system. If your running a 460, you just accept the fact that MPG's are going to be very low. Keep it tuned up, and don't pass a gas station when your gage is below 1/4 tank and you'll do fine!
My '78 F150 Supercab came from the factory with a 460/C6 setup.
It had the Motorcraft 4300 series 4v carb, with small primaries, and big mechanical secondaries, and a 3.50.1 rearend.
It would get 14-15 mpg all day on regular leaded gas, with a/c or without, city or highway, this is baised on "normal" type driving.
Your F100 being light should do the same or a hair better depending on if its been modified in any way.
I swapped the gears in mine to 3.00.1 and lost 2 full mpg due to I think taking the engine out of its optimum rpm ranges.
That '76 should be pretty much the same as my '78 was with no pollution control stuff other than a PCV valve.
Do yourself a favor.... hold out for a 351 or 400.
If the pickup you are looking at is super nice for a good, good price, the 460 is worth "living with." However, there isn't much need for a 460 in a half-ton unless you want to race around. Be ready to spend money on your tranny if that's the case.
If you have something heavy to pull around, don't buy a half-ton.
The 351/400 is a much better engine for trucks (unless those trucks are for pulling large trailers.) Parts for 351/400 are more abundant and less expensive. You will also get better mileage from the 351/400. I have a 400 and it's the best v8 I have ever owned.
Hey, does that truck have AC and cruise?? Original paint?
I get about 11 MPG with Harrison, traveling about 110 miles to work from Cartersville to Alpharetta daily. I only "get on it" when I see a corvette coming up behind me.....then they tend to vaporize in the distance...otherwise I'm easy on the gas.....
[updated:LAST EDITED ON 29-Apr-02 AT 06:59 PM (EST)]Whew! Man, I'm only getting about 5 miles per gallon in my 460. I'm burning propane so my mileage will be less anyway. The up side is I pay less for fuel. My gauge reads in percentage so I could be off a few gallons either way when I refuel. But after reading many posts on the forums about different heads, port work, gear ratios, cam timming and such, it will be interesting to see how much better I can get. Fortunately my motorcycle gets much better mileage and I ride that a whole lot more that I drive anyway.
