I HAVE A 1995 FORD F-350 4X4 WITH A 460 ENGINE AND 5 SPEED TRANY WITH 83000 MILES ON IT.I AM LOOKING TO GET A LITTLE MORE POWER OUT OF IT WITH OUT SPENDING ALOY OF $. I DON'T HAVE ALOT TO SPEND ON IT. I SOMETIMES ENTER IN A TRUCK PULL AND COULD USE A LITTLE MORE POWER.THANKS FOR YOUR HELP.

is it mass air, or speed density (lack of mass air sensor)? If it's speed ednsity that will limit the choices for upgrades such as camshaft but comp cams probably makes a speed density friendly camshaft for the 460. I know they make one for the 351 windsor and I have used it with good results.

Small stuff like a better coil and wires, bumping the timing to maybe 13 or 14 degrees initial and a larger plug gap (.045-.055) might help as well. But you might want to experiment with the timing to see if it works for you. I did these on my SD 351 windsor which is a different engine but it was within the limits of the SD system and worked well. Headers and a better exhaust are good cheaper upgrades, and shortys will work well if you don't want full length (probably cheaper and might be a direct bolt in too). Go for a 3" or 3.5 single exhaust if you don't want duals. Alot of this had been done by the guys on the bronco forum i visit and they've all been happy.

I've also heard alot of mixed results on throttle body spacers, most say it's not worth the time or money.

On the other hand, if you somehow have a mass air system, you can do alot more

All of them (the 460s) are speed density through '96... supposedly '97s are mass air systems. Seems odd that they would change it for the last year of production...

I would look at the exhaust system & exhaust manifolds first...

The only Mass Air 460s were from California. The reason was they were OBD2 to meet California emissions. They were 96 & 97s. The only diffrence was the 96s came with air injection and the 97s dident. All others were Speed Density OBD1.

Change to the very early timing gear/chain setup.Yours is retarded about 4*.That will be like taking a energy pill.

Rick, I had thought the same thing in the past, but per Paul Kane:

"Guys, the 460FI engines, as far as I know, all came with straight-up single roller timing sets. You do not need to change that out for your intended use.

I am certain about the 460FI engines having straight up roller chains for 1990 and up 460 FI engines; I would assume that these chains were used since 1988 when the FI system (and more importantly, OBD1) came out."

I've got an 88 that I'm doing about the same with as you. I was told to move the air temp. sensor from the intake to the airbox, to increase the injector's pulse width. Cost $0.

How did that work out? Or did you do it yet? Interesting mod, makes sense. Would the air temperature be that much cooler in the airbox? Would be worth a try anyways, if it didn't work would be very easy to change it back

I can tell you how to get 90lb ft tq and 53hp for under 500.00

first 20-25hp/ tq is free

On your intake tubes you will see a plastic piece Remove it cut out the silencer re-install. Remove neg batt cable for a few minutes and there you have 20-25hp & tq.

Next up is a different airbox and a better muffler & tailpipe.

I have done this to 3 95-97 Fseries 7.5's with same results. Do expect another 2-3mpg on highway too with 1-2 in town.

From there the easiest with the speed density is a blower kit. Work very well

another 70hp & 80 lb ft

Not much you can do cheap other than my first mentions. You will see a HUGE diff.

I dynoed before and after so the airbox, exhaust and silencer is no guesswork.

I just got done going through a 96 f350 4 wheel with a 460 last week for a customer. He tows a 14,000 dump trailer with it and it is gutless. It needed a lot of service plus I gave it the basic tuneup, plugs, wires cap, rotor, air filter, etc. It runs better but it's still a turd in the get up and go dept. I noticed the thing has no rear gear to it. I checked into it and it only has 3.50 gears in it. Well that kind of sucks in a 6000 pound truck with 32" tires. So he is going to drop it off this fall for a gear change to something in the 4.11 to 4.33 range. That will make the best change for hauling out of anything. I had another customer that had a 1/2 ton brand X pickup with a 350 and 3.08 gears in. He towed a 10,000 pound fifth wheel camper ( i know not good in a non-floating axle rearend) and the thing could not get out of it's own way. I put 4.11 in both ends and it was like a completely different truck. So you make want to see what you have for gears in your truck.

My 97 CA mass air F-350 w/ 460 does not have air injection. I don't know a lot of things, but I am sure of this...

I have only had the truck a couple of weeks, have not tried it yet. My dad just bought an $8000 Snap-On scanner that I'm hoping I use to can confirm a difference, but he said going back to 88 is pushing it. I'm hoping it shows the temp that the computer is reading. He's not very computer friendly, so maybe he'll let me push the buttons. Right now I'm trying to hunt down bolts for all my accessory brackets cuz the PO had it all apart "fixing" it and lost em.

Gearing is a huge part of performance.

I see headers in your future as well as mine.... PM sent about a guy I know.

Is your truck a California 460 OBD2 mas air truck? If not thats the diffrence. I have a 97 California F250 4X4 with a mas air OBD2 460 in it and it dosent have air injection. I looked in my smog book and it lists the 97 460 California (only) as being the only 460 in a light duty truck or car to ever come without air injection. The 96 California (only) 460s were OBD2 mas air but they did have air injection.
