After much searching I have come up with very little information on upgrades for a fi 460. I would like to see 300+ horse out of a 95 f350. This is more or less a farm truck so emissions are not an issue. Also I would like to keep the price for upgrades under 1500. Ive searched 460ford, and fordfuelinjection, etc. but just cant seem to come up with a build for a 460 truck motor that makes over 300 horse. Anyways I know this has had to been covered before but I cant seem to find any information so thanks for any help.

 

I'm getting ready to do some work on my '92 with pretty much the same goals, heres my plan: Thorley tri-y headers to go with the single 3" exhaust I have already, a good valve job and possibly bigger intake valves, mill about .025-.030" to increase compression (your later heads already have the bigger valves and higher compression), a mild cam like a summit K-3500 or the Comp Cams EFI compatible cam and possibly some roller rockers. I'll get a chip burned if it needs it, but I'm hoping it's ok with the stock computer..

Good luck!

 

I hope you dont mind if I follow your thread, I`m sort of in the same boat.I just got a `88 F-350 4x4 w/new motor, but it`s been sitting in the truck for a year never started because the PO gave up on hooking everything back up.I`m going to pull it soon and tear into it because I never saw the inside of a 460.I think I can convert it to MAF and do some basic hot roding like porting the heads and intake and puting bigger injectors in,adding a BBK throttle body,and headers.I still need to research a good valve train and a high torque cam.I`ll need to find out what the compression is now and probably put some higher comp.hyperutectic ones in.

 

Basically what I have found is the speed density fi really cant take anything more than a very mild cam, and if bigger injectors are used that also will give the fuel injection a fit. So it seems that most like to convert over to a maf setup but I havent seen a very good write up on how to do that. I think theres a kit out there but I think its around 1600. hopefully someone will post how they did there maf...

 

On Ebay under 460 efi there`s a company that sells MAF kits

 

with a budget of 1500 there really isnt much you can do, but if you had a bigger budget... say 2500... then you could get some nice ported/larger valve d3ve iron heads from reincarnation-automotive.com, a decent hydraulic cam, an aluminum intake, a big mass air meter, an a9l mustang mass air computer, some 32lb injectors, then you have about everything you need to run 350-400 horse and have fuel injection except the headers and exhaust... if you decided that wasnt enough for you theres always a stroker kit.

 

The biggest bang for your $$ is a set of headers. I have a 1995 460 Motorhome with the Banks Power Pack. Banks claims over 60 HP and almost 100 ft. lbs. of torque gain at the rear wheels. I believe it. My ol MH will run with a 2 valve V10 Motorhome.

The speed density will be frustrating. If you don't have access to the program it's going to make it very difficult to get 300hp and make it run right. Fagettaboutit or get mass air.

There is no reason you can't use the MAF system from a 5.0 liter Mustang or any mass air V8 Ford system you can find. If you can wire and fab at all, you can do it.

You can get those inexpensively all over the place. Even free if you're patient enough.

A turnoff for me is that the factory fuelly intake manifold is UGLY! Even if it flows ok, and it does, it's UGLY!

Go to www.massair.com they have conversion kits cheap too. Or go to ebay and type in "mustang mass air"

After the conversion getting to 300hp is easy and takes the usual performance modifications. Headers, cam, letting it breath.

for info from a guy who had good luck with a very mild build using a stock speed density setup. I'm working on duplicating his setup. I can't say if 300hp is where I'll end up, but if a stocker is 230hp, and a banks kit gets 60+hp over stock (and the banks stuff is really just headers and a single 3" exhaust..) then I'm thinking that with some easy headwork ($350 at my local machine shop), a cam and lifters ($200) and headers ($650) I should be somewhere near 300hp for less than $1400 including gaskets, oil, etc

This level of build up is what I think of as the easy gains. Pick the low hanging fruit first....

 

What about those long tube Flowtech headers on e bay, are they usable for that price or a joke & junk.

I guess I better weigh in on this one I have the same truck as oldracerguy except mine is a 5 speed with 3.55 gears. I have done the following mods K@N fuel injection intake kit with air horns removed, E7TE heads with mild port and 2.08 intake valves, speed pro cam kit #KC1086R, Doug Thorley tri-y headers and single 3" flowmaster exhaust with 70 series muffler. The cat is gone and so is the air injection. As was mentioned above the banks kit claims 60hp and 100 ft lbs so add that to the stock 230hp and 390ft lbs and I should be 300 to 325 hp and around 500 ft lbs. The truck has 196,000 miles the computer is stock and have had zero problems. And it runs like a 460 should stock it ran like it had a 302 under the hood.

I should have looked at that link above it is the post we talked about a while back. Anyway it worked for me any questions let me know

Isn't the Banks headers the same as the Thorley headers?

 

Not even close. Thorley's are Tri-Y and most of Banks are equal length long tube headers. Banks is unique in the fact that they use a 5/8" thick flange, so no gasket is required. Also Banks has the capacity to dyno test all their products on site. Another di$tinguishing feature is the price. Bank$ is really proud of all their product$.
