Hi, I'm new to the domestic world I'm a tuner. I know I know you all saying F that but a car is a car and a truck is a truck they all work the same just built by different people. Anyways I bought this utility truck to start my business but its a gas guzzler. So I'm trying to make it fuel efficient. Anyone know where I can find performance parts for a 95' f-250 460 block 7.5L engine? Main thing I'm looking for is a high torque intake manifold with 1500-6500rpm levels. I would like a long and skinny runners dual plane. im looking for torque.Smaller than stock injectors. Please help me out. Thanks!

 

You can't get there from here, a 460 is a gas guzzler and there is no changing that. The type mods you suggest are not possible for a number of reasons that we can go into if you really want to know but the bottom line is no matter what you do this motor will always be lucky to get 10mpg city.

What type of business are you starting? If you really don't need a HD truck with the biggest gas motor ever put in a consumer vehicle then I suggest you trade it for a 1/2 ton with one of the smaller motors.

 

Listen to Conanski. On the best days, my truck can manage 12 mpg down hill with a tail wind. It was my dad's farm truck for the first 14 years of it's life and I can tell you that pulling anhydrous tanks through the field, you could watch the fuel gauge drop as you drove. The only way to get a 460 to be fuel efficient is to not drive it. If you're going to actually work it, it's going to get thirsty real fast.

Another issue is the general lack of performance mods for the 460. If you're truly set on the 460, you'll be looking at a much more custom set of performance items rather than simple bolt on stuff. While the carbed 460s have a pretty good performance base, there is essentially nothing other than headers for the EFI 460 (headers would be a great investment in power, still not going to help the fuel economy). Also, your truck will be speed density and running smaller injectors isn't going to help out; while the computers aren't real capable of dealing with changes, it can compensate for the lower fuel intake. I had very worn out injectors (truck only made a 90 hp dyno pull) and I was still only getting 9-10 mpg.

If you're looking for a "fuel efficient" truck and still need a heavy duty, maybe you could look for a truck with a 351. Much better aftermarket, but still will probably only manage in the 12-14 mpg range. Otherwise, look for half ton if you can.

 

The best thing i ever saw for the 460 EFI was the system offered by BANKS. Its not realy doing much to the efi other than making the exhaust and intake more efficent. My father put this kit on he 94 RV running the 460 on a F550 chassis and he said it was a noticeable difference and he got a slight increase in fuel mileage. Banks has all the numbers listed on the website its pretty impressive, but they are proud of their stuff $$$$$$$$$.

 

There are tons of performance parts for the 460.........Do they work with SD or even MAF in our trucks? not too many. Most are meant for non-EFI and non street applications. 10/12 mpg is what a 460 gets, no way around it. As far as stock performance goes, mine will leave most passenger cars in the dust on a freeway on ramp, and has no problem towing a 2,500lbs boat and gear while hauling a 9 1/2 ft slide in camper over a 6% grade at 65mph.........just do not watch the fuel gauge while doing this. Maybe a half ton would fit your needs better?

 

I'll take it. I love the 460. I wouldn't ever think of getting decent gas mileage out of one. Of course I could care less about gas mileage, and the 460 sounds soooooooo sweet with open headers.

 

headers and if you look hard enough you can find a chip that cost 400$ and will give you 10 extra horse but it's for offroad only(will not pass smog b.s.)applications. if you want to haul and tow, suffer at the pump. if your just needing to haul light stuff get a ranger

 

Chip is garbage. They are all crap. It doesnt do anything other than advance the timing too far.Dont bother

 

yeah i would never spend that much on one anyways, i cant understand why performance parts for efi 460's is either non existent or insanely priced, try to find a set of headers for under 500$

 

Chip on any of these motors is complete horse@#$%. Just adjust the base timing out a few degrees. If you want to make some REAL HP then put some D1V3 heads on and pop up pistons and crank the timing out to 40* total with a pro-stock dual plain intake. You'll make some efficiency.

I don't joke. My Mustang is rockin a 460 with a similar set up.

 

Thanks shuttlevalve ill look into banks. I know what your all saying but there are ways to get better fuel economy. yes the truck isnt made for it that is why i plan on upping the torque changing a/f to more lean mixture and running smaller injectors with a proper tune. it wont get me alot but it will raise my fuel economy. only reason i got this truck is it was all i could afford soon as i get a chance i will be rid of it but until then i have to make due. honestly im not a fan of trucks. and with the many cars we have on our lot i realized when my 300zx hydro locked that i had no way of towing it. and my other tuner cars are out of commission and my roommates couldnt pull me with their 240sx, mazda, and ecilpse even though they have the hp. so i bought this truck for cheap. trucks are a necessity after my many poor experinces i realized this so im stuck with this truck for now. but thanks again for all your posts.

 

lawlz...

 

As already stated you're going to find there isn't much available in aftermarket performance parts for this motor. There are lots of intakes available for the carbed version but those don't fit on the EFI motor because the heads are also different.. port locations are shifted.

Longtube headers will produce TQ increases so those should definitely be on your list.

But you are pretty much on your own for a tuner, if you are really tech savvy you could utilize a Moates or Tweecer module to gain access to the EEC memory map, but you'll have to decipher it first before you can alter fuel and timing parameters as I'm not aware of anybody that has done so for this processor.

Another way around this would be to employ a programable wideband O2 sensor like the Innovate LC-1 that I have. It can be setup to simulate a narrowband sensor with the switching point at any A/F ratio you desire.. like 15:1 for example. But you have to realize that these EEC processors switch to open loop under load so while milage gains are possible for light use and cruising it is not when towing or driving agressively.
