Ford f250 351W 5.8l w/Mods 

I have a 96 Bronco 351w and had a 94 F250 also with the Windsor. The best mod you can do are the heads. The stock heads are very restricted. Open up the air flow with better heads. Install a hot ignition. I've used MSD, Motorsport plug wires and iridium plugs with good results. Consider a larger throttle body and open up the exhaust. I don't care for loud headers, but exhaust mods give some of the biggest results. My two cents.

Nice truck man. I have an 89 F-250 with a 351W and C6 automatic. It hasn't ran in about 4 or 5 years, but I am about to fix it back up. It has 384,000 miles on it, never been rebuilt or had transmission rebuilt. It's got huge gears in the rear end, so it will pull anything but a full tank of gas. haha. We used it to pull down huge barns and pull people out of ditches. We parked it because it started getting about 4 miles to the gallon.

In all honesty I use to obsess over my vehicle, adding things and modifying for the mental thrill of it. I outgrew that and wish I had used more of my common sense and saved the money and kept it fun but also practical. Life is too short, it's best to keep ahead of the curve and predict your future wants and needs and focus some on that. Life will be easier I promise.

Dude...this is a pretty good vid...I have a 91w/5.8 5 speed w/3.55's which is older than yours but its got an MSD6 box,,MSD Blaster coil,,Accel ePROM CHIP #35369 plus a jet performance module #89109 and am running a true dual exhaust w/o cat or mufflers ,,,,Just straightpipes with baffle tips but still retain the o2 sensor.......Another mod includes the IAT sensor mod where the IAT sensor is bypassed with a resistor to give the engine a richer fuel to air mix in my engine...Other mods include turning the air injection pump into a vacuum pump to suck the crankcase heat and pressure from the engine and inject it into the air instead of back through my intake...I also removed the hotwater line going into my throttle body to give the engine a cooler denser air mix aswell as done the EGR block of by sandwiching a piece of 1/16" thick aluminum in between EGR and intake to keep the exhaust gasses from entering the intake.....Its running better than 14's in the quarter all day on the stock throttle body and intake.....Seeings you have a 97 you can give that badboy some more perf with a flashpak tuner tool alot easier you do know.....right?......

I tried your idea of an adjustable air bleed for the map sensor. But I ran a vacuum hose into the cab and installed a lawn sprinkler valve and mounted it on the dash. Now I can make adjustments on the fly!

We used to have a 1997 F250 Super Duty, and we always had to order parts for a 1996, or we would get the wrong parts due to changes in 1997. The SD and HD were the last of the best body styles of the ford trucks.

very interesting. Thanks for posting. i just picked up a 95 f150 with 351

Buy the dual air filter kit for about $45 on ebay. look up ford 5.8 air intake. The bronco version works the same.

Nice truck, eventually throw a new bed on it but they do make a aluminum underdrive pulley kit for it from BBC and also get you some long tube headers (stainless ebay - $142) and you'll notice some good games with those two together, maybe later a fat cam and some lightweight trik flo heads! Yum🍺👍

I just put traction bars on this truck, HUGE difference, new video coming soon.

Thank you now I know where to start on my 89 250

Nice mods bro sounds great runs nice and it’s a Ford nice man thanks helps me a lot w what to do w mine

Thanks I have almost the exact same truck! I will be doing similar things to mine this summer. I am going to need to beef up my motor for farmwork and towing/hauling.

351w kick ass. nice video cool mods

When adjusting timing on a 1996 and later ford, OBDII, you need to unplug the SPOUT connecttor FIRST before moving the distributor...It's a small grey, inline plug, usually need the firewall/brak booster and fender.. google it!! Otherwise the computer stes it right back to where it was...

I have not found one. Buy the 2nd alternator and take your truck to a good machine shop and they could make you a bracket for $200 or 300 no problem.

They do pretty good, It will get dirty faster, but I wouldn't worry about it unless your on dirt roads all the time. You can also get these things called pre-filters which are good blocking large particles. They are kind of like a sock. They keep your cone filter clean a lot longer, plus a prefilter is easier to clean.

The only thing hard about it is I had all the air injection BS in the way. On the 5.0 that's not there so it will be a lot easier for you. It also gives you a chance to look at your injectors. I had one that was about 80% gummed up at the tip. The injectors just slide in and out, so they remove easy, the fuel rail hold them it. You'll need fuel line separator tool for the two fuel lines, which are round plastic things that cost like $10 for a set. also lock washer and lock tight intake bolts.

We have a 1993 F250 4x4 lifted w 35's w same 5.8. 240,000 miles and slower than molasses. Have had it to the mechanic a few times w no improvement. It won't even get out of it's own way! :( Going to have hubby try a few of these simple things and see if it improves. He's doing the cold air intake today and will have him look into shortening that cable. And as for all the assholes saying don't spend your money...IDK why they're worried about it. It' YOUR truck & YOUR money. TY for the video.

I used a 5.0 intake tee, and tb hoses, and mounted an open cone to the end of the tee. The cone sits on top of the alternator. Yes, it's a WAI, but will give you some top-end gain, and slightly better gas mileage (and faster warmup). I believe the tee opening is 3.5" but I don't recall. Either way, I noticed a difference on mine.

Nice mods man, ive looking for stuff to do to my truck! Your video helped out alot, i will doing the same thing now

Get a 101mm throttle body and intake

So the exhaust setup is just a muffler delete? Everything else is stock?

Edel-Brock... not Elde-brock. Great vid though

I have the K & N now, I've gotta make a video on it because out of the box the ID to throttle body is way undersized due to injection molding being way to thick there. I had to use a 2 and 1/8ths hole saw to bore it out to match and then polish it back out. Also the intake was much quieter with the all plastic intake. I only bought it so I could run a single nozzle wet nitrous system in the future, and it looks way better than the twin tube.

just bought a 1988 f.250 with a 5.8l Windsor, 2 wd on gasoline. but it has a utility bed on it,which is one the reasons i bought it. im sure it weighs alot more plus tools and equipment. are there any good ideas for my trucks performance? i already replaced fuel pump,starter and now my harmonic balancer seperated and im replacing it today. thanks

Hello....first of all your video was great but I do have a question. I'm pretty sure that this year of engine for Ford was Speed Density (SD).......by changing the intake/airbox did you have any issues from the ECM? It seems everything I read indicates you have to be careful when modifying these concerning airflow/vacuum.

I have a 4x4 XLT with the same engine. I want to rebuild it essentially from the ground up, starting with the motor. I really want to get rid of extra stuff in the engine bay just for simplicity and I'd like to know if you have any ideas or tips. Any way to get rid of the air injection system and vacuum lines?

Love 351 Windsors!! (AKA 5.8) Lot's of ways to wake up these old truck motors. The roller cam motors were only made for like 4 years in the mid 90's and they are still a best kept secret it seems. No I don't work for this magazine. lol I am posting it here as just one reference for fellow Ford freaks who want to wake up a sleepy low compression 5.8/351 Truck motor: www.hotrod.com/articles/build-a-505hp-ford-351-windsor/

LOVE MY FORD

I got the same truck but white and I love it it's still stock right now but I just got it as my first truck but I wanna model it

Engine sounds good bro

Have the same truck but red and lifted by a few inches took the hub caps off

So the only mods you have are intake, throttle body and air filter sounds sick

Super glue? I've never used super glue on any engine. Is that a good idea?

I'm so jealous

I want to do the same intake and thottle body to my 95 4x4 351W. Its was rebuilt last year with a .477 lift cam and MAF conversion .

Ivegot an 89 e 250 4x4 van with 351 , I could use all this ! Dang ! Just pull The darn thing out the front and start from there I guess !

When you put the BBK throttle body on did you have to put bigger fuel injectors?

1993 F250 351W XL. Any way I could get some help figuring out where this last wire goes? Runs off the main wiring harness (same harness as the injectors, drivers side) everything is plugged in except this last wire and I can not find where it goes. Injectors, and everything on the front I'd plugged in. The wire not plugged in is about 8-10" long and has a tapered side to it. The plug itself is rectangular but the portion that goes into the female end is tapered. If anyone can help it would be extremely appreciated.

get a full high output ignition and run it with autolite copper plugs with the gaps opened up a little past stock

There are many ways to remove the air injection, search of it on the web you'll get lots of forum posts. There are pros and cons, like legality. I would like to remove it too, but I won't unless it fails.

Do you know if the 351w in these trucks had roller lifters? Or was that only the lightning and maybe the bronco?

That's cool, I've been wanting to do a front end swap on a blown up 4wd.

I have the same truck, but automatic. 97 F-250HD. I'm looking to start upgrading it, do you have any suggestions? I want to upgrade pretty much everything, just not sure where to start.

I noticed on mine the vac advance was locked with a plate that says octane 0. Would it be possible to use a vac advance model with efi? I've only worked with carbs in the past.

You can put e85 efi's on these engines

I have a 97 f250 HD 4x4 with essentially the same engine. You're running stock exhaust manifolds? And a roller cam? The pipe off off the cat to the side is a great mod too.

I just bought the exact same thing (mine is an XL though, I wish it had a tach like yours) '97 RCLB 2wd 5.8L 5spd 3.55 open diff. Why didn't you delete all the emissions stuff, delete the cat and run dual pipes? Since these have OBD II can they be ecu tuned on a dyno? You considered cam and headers? I was thinking about trying $400 remaned GT40P heads or ebay special 195cc aluminum heads that go for $700 complete. I was thinking about trying a 228/232 114 cam like Richard Holdner used in his big bang 351w as well. I am a lot more familiar with LS stuff, my other truck is a 2003 6L Silverado 2500 and I have a 2004 GTO 6spd. I got the F250 yesterday, it has 219,xxx miles and I paid $2300 for it. It needs to be cleaned up but, it is way better mechanically than I expected it would be, I drove it home 3.5hrs with no issues, except the headlights get really bright when the rpms are up, maybe a voltage regulator? What rpms does your truck show when it hits the governor? Mine reads around 78mph in 3rd and I figured 4750 using a gearing calculator with 3.55s and stock 235/85 16s, it has 265/75 16s on it which are nearly the same overall diameter. I am giving you a sub and I would like to start making RU-vid videos again in the vein of Zip Ties and Bias plies, Vice Grip Garage, DeBoss, Uncle Tony and the Roadkill family. Your build has given me some good ideas to build on and the truck definitely has some poke. Thanks for sharing.

quick question I was wondering on the cold air intake how does it hold up to dirt roads being that your air filters are out there in the open? I have been wondering bout this and is only thing keeping me from doing a cold air intake.. of course you can blow the dust out with compressed air or something just wondering how they hold up thanks

What kind of intake and throttle body are thoes ,?

a race/farm truck? i love it XD

1992 Ford F250 5.0L 4x4. Need to.know.where all the fuses and regulators are located. Can some please help me?

The SD engines will never see any performance increases. The computer can't adjust for it.

I am assuming all if not most EFI 351W 5.8L's are the same. Im doing a build myself on my 97 F250 and i found the exact intake set up as you but the website is telling me the ending year these will fit is 96.

How was the stock intake manifold to take off? I need to access my injectors on the passenger side bank.

Great video man. I have the same set up on my 89 but the old owner had done a maf conversion with a 95 mustang ecm and now it has parasitic draws. Im swapping to stock wiring and ecm. How does it run with the original vacuum set up without all the needles mods you did? Lean Or normal?

Lookin at one of these for $2500 on CL...How often do you fill the tank? High school student making a bit more than minimum wage and my Maxima is legitimately falling apart! Thanks!

whos Elder Brock?

What is that little hose connected to on the throttle body I found a 250 with same throttle body but there’s no line hooked up

I have this same set up on my 95 f350 5.8 but ever since I did this my egr valve wants to open up on idle not all the time I can go days with no problem did you ever have this happen?

If you want horsepower........take off the cat.

Hey do you know what’s the difference between the 5.0 and 5.8 upper intake manifold

Did you put a lower intake manifold on or just the upper?

i have 1992 f150 5.0 v8 and i have the bbk 56mm and i have supercomp hooker heddes and flowmaster 40s with k&N, plush hp chip, with msd coil and mallery hot box. so how hard was it to put on the edelbrock intake

Did you install the lsd or did it come with it from the factory? I just bought a 97 f250 HD and I'm not sure if it's got lsd

Should you change any spark plugs or difference off spark plugs and wires and cap for performance

headers are good too

New Shocks will fix or minimize wheel hop.

Any suggestions, advice, etc regarding radiator

You mentioned, the advanced part. But, how do they advance? I’m trying to fix my truck

What kind of normal driving mpg do you get with this?

What the has mileage with your mods

I don't think it's a 97 looks to be 96 or under 97 head light would be different

Do you have a part# for intake plenum?

1 have a 1989 ford E250 with the same engine. Because it's a van it has far less space available in the engine compartment. I REALLY want extra power out of my engine because 200hp is just WAY too low

what geabrox ?? thanks

What's your rpm at idle since you have advanced your timing. and do you know the exact degree you advanced it to.

Hello are you still around?...

whats the details on how you made that T joint to richen up the fuel mixture

Thats awsome bud. im going to do the same to mine now... giver shit!

How much did this setup cost you

can I do this to a 98 f250 5.4

how do you have the egr set up?

Total cost?

Where’s the Dino numbers

id take the cat off and put on a magnaflow muffler

EDLEBROCK, " EH-DEL-BROCK " NOT ELDER-BROCK.

You're not getting 300hp from a throttle body and a timing advance my friend lol

What would be the best heads to go with this setup?

Driving is a responsibility, risking your life and others. It's not a race track. American cars are already well powered.

sweet man, building a 5.8l in my e150. check out my channel also

ETC 8558

Seems to me you are spending money to messing up a nice stock vehicle that engineers designed just right. Save your money for retirement or a house purchase or some other thing that will serve you much better.

i had a stock pickupjust like that but it was white

you should delete all of your smog equipment, egr, cat, air injection, all of it.

I took all air pollution bullshit off you have to reroute your fan belt but it will free up some power if you put on some headers I did headers on mine straight to some cherry bombs no cats on it I punched my cats out that way they look like they're still on there

No disrespect. But they call it a "Cold air intake" for a reason. The way u have ur air filters sitting. There sucking up hot air off the motor. You need to move them to the outside of the engine bay.

What gear?
