been thinking about putting a 460 in an f-150 for a nice fast truck. whats the pros and cons to doing this? is it possible to get 12 mpg out of a truck with a 460? i know i want to go carb, and i dont need more than 375-400 hp. btw, this will be a daily driver. what do you guys think?

 

Properly tuned you can get 12 on the highway. Around town 8 is a good figure. You will love the power. I put one in my 7300 pound van and it rods around like a car now. I used a Holley 750 on a Stealth to bring out all the stock engine has to offer without losing drivability or low end torque. A cam and a looser converter would really wake it up. I haven't tried headers or porting the exhaust on this one yet.

 

I can average 12mpg with my 3/4 ton 4X4 with the 460. I am glad I didnt get a 351, cause my dad has one and he gets the same mileage with less power.

There are no "cons" going to a 460 .

No replacement for displacement.

 

fordmarshall111 ~ true, there are no "cons" when it comes to stuffing the asphalt churning, stump pulling 460 into an F-100 / F-150. I love my conversion - I can run WITH the pack whenever **I** choose to, or become LEADER of the pack whenever **I** choose too and he is a street-sleeping daily driver. I rarely run him "off idle" and will probably never wind it up "all the way" (too much power). Check him out in my gallery....

I get about 10 miles per gallon and he's "fairly well built".

 

i went from a stock 400m to a stock 460, and there is a HUGE difference. Way more power, same mileage. Like he said, there are no "cons". What motor is already in ur truck fordmarshall111 ?

The same with my 82. I swapped the 400 for the 460. The 460 actually gets 1 -2 mpg better than the 400 ever did.

And no comparison for power.

 

I have a 1979 F250 with 460.some one sells bolt on EFI with turbo to update old 460's for about $800. Supposed to be do it your self. Takes HP from 225 to 450. Mine runs on propane and I get 8 miles to the gallon.

 

That's quiet a jump in HP. Is that really do-able with just a bolt on and if so, who sells it?

 

I saw them on S.peed TV.Like a dummy I didn't write down the name. They had a lot of different engines on that show by same after market company.
