It is speed density, and I have a 5 speed, planning on doing a ZF swap in the future. What could I do about the computer situation? And about how long would I be into the swap alone?

Where are you at as far as maintenance ?
-plugs
-wires
-dist. Cap and rotor
-ign coil
-tranny fluid
-oil
Etc.

My 5.0 has no problems going anywhere or doing anything. It will even haul a little ***, not a lot but a little haha. Do a sixliter tune up and maybe some other maintenance and small mods and it should be able to do whatever you need it to.

New plugs and wires about 2k ago with cap rotor and coil , always ran amsoil in my engine and royal purple in the trans t case and diffs. Mines fairly quick, but it doesn't have good passing power or do very good going up hills. I'm wanting some more.. Drop a gear and put you in your seat kind of power

Having the 5 speed in your truck makes it even easier to swap computers.

If you plan on building a power house 351W you will most likely want to swap to Mass Air....That's another project I plan on undertaking in the future. You could do a Mustang 5.0L Mustang Mass Air Conversion on it.

Although, speed Density is plenty capable of producing plenty of power.....All you need is a 5.8L Speed Density truck computer...Any one of them will run the truck. Some will run it better. I would not recommend one for an E4OD. Although it will work. IT might throw a code and think the trans is in Neutral when driving down the road.

Like I said before...Check the information from other sources before you act.

Yep, 460's stock published horsepower numbers were low, but they make up for it in torque from idle on up....I pulled my 6k+ pound Airstream up into the mountains yesterday. My 460 sure did a fine job,like it always has ....Yep, gas mileage is never great. Mine will get 14-15 running empty on the interstate. Towing is 9 -12 on the interstate depending on the speed I run.

Sorry was late last night, wiring harness are different on some years...OBD2 such as 96 and 97...

All fine and well, it's understood.. When it comes to computers I'm clueless. I've had people tell me that swapping computers takes all kinds of wiring and rearranging. I'd do it if I have to but I'd rather not, A MAF swap was considered in the past, but the kit to do it was about $600, and I haven't been able to find any forums where people did it with scrap yard parts. If I can build it up to around the 300-350 horsepower mark with speed density Id like to do that. Driving out of town today I literally couldn't exceed 60 because the wind was blowing.. I would like to remedy issues like this. Thanks again guys!

Put trick flow heads on it. Upgrade the cam on it. Not one of those Lopey e303 cams. Those are for a mustang. Powerband on those do nothing good for a truck. Upgrade those two. Advance timing a couple degrees. Maybe a hotter ign. Coil. Gap the plugs to about .50. And maybe even upgrade the injectors. All of that combined with what you already have will more than likely give you what you what youre looking for.

If you had a E4OD transmission it would be a different story I'm telling you.

Any 5.8L speed Density computer is plug and play on your truck...The 5.0L and 5.8L speed density computers are Banked fired on the injectors. All left bank injectors fire..Then all right bank injectors fire. You don't have to worry about wiring issues with speed density on a 5.0 to 5.8L engine swap with a standard Trans.

Now for Mass Air...Just do what the Mustang guys do when they swap their 5.0L engines to Mass Air.

1. Mustang Mass Air Conversion Wiring Harness

2. Manual Transmission Mustang Computer/ECU– A9L Code

3. Mass Air Meter – needs to be programmed either for stock 19lb injectors or 24lb injectors. The stock 5.8L F4TE Roller engine is fine for a stock mass air meter programmed for 19lb injectors. If you swap the Intake Manifold and put aftermarket heads on a 351W you will need 24LB injectors most likely. It will run with 19lb injectors. But if you get on it full throttle you may burn a cylinder because the injectors will be pretty much be maxed out.

4. Cold Air Intake or mass air truck intake tube and air box.

Other parts might be needed but every thing should be pretty much plug and play with your truck having a standard Trans.

Having a single throttle body design makes it easier compared to the dual throttle body for parts and modifications. Although, for low end Torque the Dual throttle body and long runner design of the upper intake manifold works perfect. Other then that the 5.8L lower intake manifold is crap and chokes the engine to death along with the crappy E7 heads they put on them. If you do a 351W swap I would swap intake Manifolds to a single throttle body design similar to the 93-95 SVT Lightnings or Mustang just to be able to interchange parts easier. I'm just gonna use the Edelbrock truck intake manifold since my Long Tube headers have the EGR tube going in the header.

To do that you would have to have:

1. Upper and lower intake manifold for a 351W.
2. Single throttle body, "port-gasket matched with intake manifold."
3. EGR Spacer that goes between throttle body and intake manifold... The single throttle body designed intake Manifolds have the EGR usually in the lower Intake Manifold. Unlike the 351W trucks which are usually in the Passenger side Header.
4. Your stock Throttle cable should work if not one for a 93-95 SVT ford Lightning should be fine . The only problem is the Throttle cable bracket will have to be custom made or one bought for a SVT lightning...Just cut your factory one with a die grinder and weld it back together would be what I would do.
5. New Vacuum and EGR hoses.
6. Also, you might have to have a Vacuum tree installed. For all the vacuum lines that route out from our trucks
7. Valve covers...This depends if you have the Air tube and breather boxed swapped to the passenger side like the mustangs have.

As before, I am not certified nor an expert in this field. This is stuff that I have read in the past and retained by memory. I do not know if it is correct so do your own homework.

What kind of cams do you recommend?
