I think the washers do the trick just beautifully, brother. I would love to run this 351 swapped monster just to feel that monstrous torque at my fingertips :D
This video is old, but the info in here is solid Gold!!! Saving this video for my 460 to 351 stroker swap. Thanks very much! Loved the Headers install Video too. Great info a must to watch. Thanks so much. Cheers from Motown.
@@BMF_Garage Thank you!!! New subscriber here. Got some binge video watching to do brother. What does BMF refer to please? I have been racking my brain on that. lol
i just bought a 87 lx and after watching the first video i think ill go with the 302, im not really after any huge numbers i just want something thats really fun to drive
The torque is what I like. A stroked 408 is bout the same cost as a stroked 347. There’s no replacement for displacement. More torque with the bigger cubes
B Stang, I am wrapping up my 408w efi setup and I have the same intake as you except I have a custom cam and heads. Do you think my car will have a hard time starting up on the stock ecu for a break in run? I will be using the 302 injectors/no tune just plug and crank.I have a megasquirt but haven't installed it yet.
Your 408 be sucking in a lot more air than the 302..... If your ecu is mass air then it should work ok. I would suggest something to monitor AFR while doing so just to be on the safe side though.... Let me know how it works out.
I just changed the k member to drop mine down to use the stock hood, while the k member was out, I upgraded my suspension (front and back) the 351 was supped up a bit and I had to rebuild the tranny to handle the 351 because it destroyed the stock tranny Over all I spend about $8-9k to get the stock hood, suspension, custom headers and a tranny to handle 650tq in case I throw in a blower, I’m at 383 at the wheels now
You couldve saved 2inches if u used a 3848 elbow instead and itwould still have room for throttle body linkage and you would've been able to avoid using the washers between frame n k
lots of great info here. i traded a 79 chevy 4x4 for a 88 ford f 250. was going to put the chevy 350 in my camaro then i got to thinking. 351 in the mustang??? Ya! good to know i made the right move. always wanted a cobra r hood so im good on that part. only thing is that my 302 is pretty hot so i will have to do something with the 351 to make it worth my while. nit sure my rv cam would be good in the 351 yet but i bet my heads would help. worked over 95 heads on a 86 block. will be the third motor them heads have been on lol.
+Vapers Win you definitely made the right choice! I'd be interested to see what the 95 heads do on the 351w. Might be good, or could be a bit restrictive with the extra cubes.... Nothing a turbo couldn't fix!!! Good luck, and let me know how it goes!
I've had a 351w that was in a 83 notchback that I used to have I got rid of the car but kept the engine. Man do I wish that I kept that notchback who would have known
hey question for you I got a 4 banger 87 swapping a 351w just got a torker 2 and 650 edelbrock was just wondering what heads and cam I should run for maximum power and ok drivability it's gonna mostly be a strip car but go to cruise night once in a while thanks great video
Curious if the subframe from the SN 95 has more oil pan clearance and if the steering rack shaft is offset more with the bigger mod motor? Anyone have any information, I'll have to do some measurements at the junkyard this week! Swap the whole damn front end and get the bigger brakes and wider stance at the hubs!
Im not sure on that. I have seen both convertible and non convertible engine mounts and there arent any noticeable differences between the two. Both look to be the "captured" style mount and both look to have the same dimensions...
After spacing my sway bar down, I learned that the sway bar mount from an sn95 bolts in place of the fox mount and does the same thing. All comes down to how much you can spend. If I would have known that the SMR solid mounts would cause the oil pan to contact the steering rack, probably would of went a different route. The energy suspension mounts are great pieces, especially for the money.
Thanks for the info on wiring, I didn't know everything would just switch over to the 351. I thought i would need the whole harness out of a truck. Does the larger displacement mess with the ecu?
Hey B Stang, great videos. I was looking for some info, seems like you should be able to help. I have a bunch of gbody friends going LS and they try to convince me to go LS but I really want to go 408w. only problem is I don't really have the ford money. Any ideas for a good block that won't run me thousands? I'm also looking to do mostly Trick Flow products and a procharger. Your videos definetly help!
Matt Depner stock 351w block will handle a good amount of power.... around the 800 mark if you keep the rpms reasonable. I've got a stock 351 block that's a 408 and regularly revs to 7000. 550 hp engine with a supercharger. That's my suggestion!
Hey man curious about how you like your motor mounts. I bought some MM solid mounts but I want a decent street driven car. If you had the chance to do it again would you stay solid or go a different way like poly or stock
Hey buddy, I have a question for you. Is that intake combo worth it?Could I use it ,but with a split plenum intake??Will it sacrifice low end torque??I would appreciate your input on this set up!Thanks. Car looks sweet by the way!
Thanks Frank! I really liked the combo..... I felt like I gained HP and TQ when I switched tho this setup. I never dyno'd it like this, but seat of the pants was great! I think with something like this, you may lose a bit of torque with the shorter runners, but you gain a little top end HP so it evens out. I'm not sure on the split plenum setup, but I don't see why it wouldn't work....
That looks great, my friend! I had originally been planning on doing a modular swap into a Fox Body Mustang; however, I've been looking at sticking with the pushrod and either going with forced induction (which I might end up doing anyhow, but this will be my daily driver and I have almost 50 miles of driving to do each day to and from work so the car has to be reliable lol) or going with a 351 swap into the '86 Mustang GT. I wanted to ask if you happened to put it on the dyno or if you had any guesstimates as to how much torque and hp you picked up with just the 351 swap not taking into account any of the other work you did to it after that, sir? I am looking at my '86 GT which has all of the basic bolt-ons you can get and seeing what a 351 swap would do for me. That way, I could stick with the pushrod and stay naturally aspirated at least until I can save up over $8500 or so to begin going down the forced induction route with either the 5.0 (it is bored to 306 so not a pure 302) and perhaps going with a turbocharger setup - or I really like the old school vortech supercharger setups man, but I don't know - or with the 351w if/when I happen to swap that out if it really makes a massive difference. Since this will remain my daily driver for a good amount of time, I don't think I am going to be looking to push some kind of massive amount of hp through it by getting a really hot cam or pushing a lot of boost either with a s/c or t/c, but what do you guys think I can get with a 351w swap with all the bolt-ons? Thanks so much for the info!
The 351w in stock form with no blower was about 280 hp and 360 ft lbs vs the 200 hp and 250 ft lbs. that’s with gt40 heads and intake though. Stock 351w heads give a bit less hp. The main benefit from the 351w is the block strength. If you go with forced induction, the stock 351w block is far stronger...
@Clevor BMF - Thank you, sir! That is perfect, so adding over 50% more torque and close to 45% more hp is what i would want there. I really have to just keep rewatching your video because it is a thing of beauty :) If I could ask one more thing - how much do you think it would run me for parts grabbing the 351w out of a junkyard and throwing on the hotter heads/headers from my Mustang with the swap package? Thanks again, my friend! Happy driving :)
@@mihaeltomasovic thanks for the kind words :) depending on where you get parts from.... the 351w intake manifold is the most expensive part of the package... I bought my entire engine and trans package for 3000 with the ecu and wiring harness... finding a used lightning lower and upper is around 500 and up now days.... you can always buy a new edelbrock or trick flow manifold but they are around 7-800... the cheapest option is something like the carb style efi intake manifold...
@Clevor BMF - Thank you, sir! That is great advice and information! I am in a bit of a pickle right now as I live in an apartment complex that doesn't allow me to work on my car in the parking lot... I could either rent out garage space which would cost a ton of money and try to teach myself a lot of this stuff, or I could just pony up the dough and get it swapped by a buddy of mine who specializes in Fox Body Mustangs and particularly in Modular Swaps; however, he can do any type of swap so I'm thinking he would be able to do the 351w swap... Also, I really want it to be as reliable as possible, so, while I am going to get a hotter cam and use the GT40 heads, I really am going to try to make the safest alterations I can... So, I think a good intake manifold will be needed to be able to get me up close to 375hp... However, I know the torque in the 351w is just beautiful and that is what I really can't wait to feel in all honesty. I have done almost all the bolt-ons possible to my '86 306 stang, but it still isn't making the torque (or hp) that the 351w will make before even going further with more parts for it... I am hoping my t5 will hold on for a little while longer, but I think it is really not going to be able to handle it so I am in the market for a new five speed transmission (or six speed if possible LOL). I remember you mentioning it in another video, my friend, but I cannot recall if you said whether you had a manual or automatic transmission - and which one you are using right now, bro? Thanks _so_ much for all of the information and I will be making a video of my own when the swap is complete :) I am in Aurora, CO, but I hope we can get in touch and talk Mustangs or cars in general or whatever you'd like, @Clevor BMF :) Take care, good sir! Sincerely,Kris
@@mihaeltomasovic Always up for meetng new mustang people! Our mustang group in northern colorado is called Horseplay Mustang club of northern Colorado. Look us up! Also, I'm currently using a tko600 in my car... Love it thus far!!.
Hey Clevor, my uncle did this swap for me in my 89 convertible but missed a few things like swapping headers and using the correct flywheel. The issue I'm having is the headers rubbing on the steering shaft. I have a carb setup so I don't have any hood clearance issues, so I was thinking of running the polyurethane mounts because they're taller. I'm not sure what mounts are on there now, but the headers also touch the shock tower on the passenger side, so I'm thinking stock convertible ones. That's pretty much my biggest issue. The vibration from the wrong flywheel is a simple fix. Would raising the engine with the taller mounts get rid of the steering shaft rub?
You can either use mounts that are taller, or shim them with spacers to get them up. Personally I'd use shims on the mount where it meets the block and use longer bolts. That'll lift the engine up for clearance
Your great a explanations. Easy to listen to. Why not go with an oil pan that is modified? Instead of playing with k frames and spacers. Can the upper and lower stock 87-93 upper and lower intake work?
Great video, thanks! I have a build 351w I'm looking to put into a fox body style mustang. Do you know of any particular years that are preferable for ease of installation? My engine has about 400 hp and 400 ft pds of torque. I plan on making it a daily driver/toy. Also, how much additional power is your turbo providing, total power? Did you get it finished?
Thanks! All foxbody mustangs are going to require about the same amount of work. This setup was only about 400 whp after the supercharger was going. Was only about 5-6 psi. I've since upgraded to a 408 stroker and a bigger supercharger making more boost. Haven't had it on a dyno yet, just getting it tuned and on the road.
I just bought a 89 with the 2.3 in it and want to 351 carb (heard it was easier and I like the smell) I don't even know where to start this is my first build ... Any advice ..
Nook Lemniscate Make sure you check the link in my description if this is your first build. Latemodel Restoration has a great list of parts for the swap. A stock 351w from a truck or car with factory heads wont be much of a power difference than a stock 302 from a foxbody (depending on the 351w of course, but in general this is true). Get a good set of heads and an intake that will breathe well and you'll be very happy with the extra torque you'll get. depending on your intake manifold, carb, and air filter choice you wont have much room under the stock hood. Be patient during your build and research the 351w so you get the right parts the first time. And, enjoy yourself.
Hey man thanks for the helpful video. I'm doing a 351w swap and I want to run a carb style efi intake like yours. Did your computer run okay with an intake like that? or did u have to get it tuned?
Yeah, you can definitely get away with just doing that... the only thing that might cause issues is if your injectors are too big for the application... then you might need a tune.... I didn't with mine, but I only went to 24 lb injectors. was probably a little lean, but worked ok until my next upgrade.
Cool I was thinking of just doing 24 or 30lbs injectors. It's a fairly mild combo, I just have some 351 d0oe heads I ported for it. Havnt picked a cam yet might even reuse the e cam from my 5.0 for a while to get it running sooner. How's the low end with it? I've got 4.10s and a 5 speed so I'm not really that worried about it but curious how it compared to the gt40 intake. I want to supercharge later on so I'm wanting to get an intake I can grow into.
I'm going with a 351w with a turbo for my sn95 with a t5. I'd prefer efi over carbed. would i have to get new wiring for a new ecu or can i use the stock ecu that came with my 302 in my 95?
Wouldn’t be that tough. The 94-95 s351 came with a 351w, so it’ll fit in the sn95 cars. The tricky part would be wiring up the efi for the 351, depending on what setup you go with.... you should be able to use the same 351w swap parts for a foxbody in you SN95. The 351 block/engine year is debatable.. almost all are flat tappet cams, so if you want a roller you need to do a conversion (not a big deal). I’d use the 90s blocks/engine just because of the availability. Hope that helps!
i got the 351w out of my 1996 f250. if i was going to go fuel injected in a 1967 . mustang what would i have to do to the harness to make the car fuel injected. its my first swap and i don't want to mess up. i know some what about wiring. but, never done it can you help?
One thing I have heard different things about, maybe you can clear it up. I have the 5.0 ho in my 93 and I want to keep fuel injection. Will the lower intake bolt up to a 351? I would want to pick up a gt40 off an explorer, would that work? Or are they different for the 351? Same issue with heads, will any 5.0 head work? Thanks a lot, and nice looking car
The 351w has a taller deck height than a 302, so that makes the lower intake not work... The only EFI gt40 intake that they make for a 351W was on the lightning. They are the most low profile and help keep stock hood. The aftermarket EFI intakes for the 351w are slightly taller and usually require an aftermarket hood. Summit Racing and Jegs sell a good variety of EFI 351w intakes. You can however bolt a 302 upper to a 351 lower, provided the ports match.. As in, you would want a 302 gt40 upper to a 351 gt40 lower. Any heads from a 302 will work on a 351w, but the head bolts are 1/2" so you usually need to drill them out slightly. Otherwise they don't require any mods.
+Nick English Well, you can use the manifolds from a 302 from what i've heard. The main difference in the 302 and 351w is the deck height of the block. this will cause the stock 302 manifolds to sit a little higher and may cause some clearance issues with the h pipe. I used the stock 351w manifolds from the 93 lightning i got the engine from initially... but later switched to the 351w swap headers so i could use 302 h pipe and cat back...
if I find a 351w (like out of a truck) what all do I have to change on the motor besides oil pan to get it to fit in a sn95? can I keep my 5.0 computer or do I have to get the computer out of the vehicle the engine came out of?
Well, that's kind of a vague question... I'd start by watching my other video.... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8zgGe2bfnK4.html As far as the 5.0 computer, yes you can use that and the associated wiring harness, but how well it will work depends on whether it's speed density or mass air, and also how modified you make the 351w. The 351w will run on the stock ecu, but to run it's best you'll likely need a tune. The ecu from the vehicle it came from would work, but the pin out on the ecu is slightly different so you'd need the wiring harness as well and that's a huge undertaking to wire it all in...... 1. The truck intake is very tall, so you'll need a new one unless you're going hoodless.... 2. You'll need a 351w swap oil pan to fit around the k member of teh foxbody... 3. Depending on what type of exhaust you plan to run, you may need a different style of headers... There are a lot of variable here depending on your budget..... I'd highly suggest determining your budget and answering some of the questions for yourself that I pose in my other video, prior to deciding on which way to go... There are a lot of ways to save money, or spend money dending on which way you go.
I had never done the swap and there wasn't a ton of info out there about problems people had doing it.... Hence my video... To help others avoid the problems.
+B Stang Probably gives the engine a lower center of gravity which would be beneficial to the handling but i doubt it's really actual noticeable but some autocross junkie would probably like knowing that .
+Zachary Andrew When you run a blower made for a 302 on a 351, you end up with the blower being higher than normal due to the taller deck height of the 351w. the blower ends up hitting on the hood and there isnt a cowl you can use to get it to fit since its so far towards the front of the engine bay. I could have modified the supercharger bracket, or space the k member down. spacing the k member down gave me two benefits... one being that the stock hood fit and two being that the supercharger cleared and I didnt have to modify the bracket. Killed two birds with one stone.
+jarqu14 spacing my k member down, using drop motor mounts, and using the steering rack bushings gave me a lot more clearance under the hood for my blower setup without needing to modify my supercharger bracket to get anything to fit. With the taller 351w deck height, its challenging to fit the 302 made brackets under the hood without doing what I did.
I have a 351 @ my house from a truck. My plan is aftermarket heads, cam, intake, injectors. I want 400rwhp, I heard it's possible with a 351. What would you think? Any advice is appreciated, thanks.
+Wesley Marion Jr. Easy deal. Decent set of off the shelf heads like afr 205's, good cam like tfs1, and trick flow r intake would get you really close to that. throw in some boost and you'd be way over your mark.
+B Stang thanks for the quick reply. I'm debating between going turbo with the 302 or built 351. I know I want 400s to the wheel, just trying to see what is the better option for the $.
The cheaper bet is on the 302 with turbo. Safer bet is with the 351w and a turbo. Stock 351w block can easily handle 2-300 more hp/tq than a stock 302 block.
+jesse kaiser physical parts depend on your exact requirements.... stock 302 motor mounts fit the 351w, so you can use those but they can can cause clearance issues if youre using the stock hood (depending on your intake setup). There are solid drop mounts and fox body convertible mounts that some have use to clear a stock hood. There is also a k member spacer kit that you can get if you really want to use a stock hood. 351w has a taller deck height than a 302 so youll need 351w swap headers to connect to a 302 factory style exhaust. you'll need a 157 tooth 28oz balance flexplate if youre going auto. that'll bolt up to the torque converter already in the auto you have. The last consideration in whether youre going efi or carb. I've got another video detailing efi swap tips for the 351w if that's the route you go.
Depends on how many accessories you want to run. The stock foxbody brackets work. You’ll have to measure for the belt and get the right length from the parts store
I bought the engine and trans here as a package with the wiring harness, ecu, all the other associated wiring, accessories, etc... shipped to my door for 1800. I was starting with a v6 car so i needed everything. Has since went through a lot of changes...
Narrow your search on summit racing down to 5.8L efi intakes. If you like the elbow style, that’s called the edelbrock super victor but you also have to buy the elbow separate. The lower portion of the intake manifold is the difference on a 351w. It’s wider than a 302.... to save some money, you can look at different Facebook pages and craigslist for used ones..... the gt40 from a first gen lightning is a popular one but it’s getting rare and about as expensive as new manifolds.
I have a 351w swap with gt40 upper and lower and my 3inch cowl still hits lol BUT I ran a truck fuel rail and had to use a 1 inch plenum spacer to clear the fuel pressure regulator and fuel lines. So kind of my fault. BUT yet again my fuel lines are a lot more simple to run since I used a 1996 v6 mustang fuel system lol and just had a revelation as I typed this... I didnt think to put a gt fuel pump in it.... FUCK!!!! Lol oh well. Oh and another thing, I got convertible mounts and a UPR k member and I did have to make half inch spacers to raise the motor to clear my oil pan and ding my header on tube 7? like everyone usually has to to clear steering shaft. EDIT just figured out the v6 and 4.6l v8 use the same fuel pump. shew. it'll do for now till mods out run the pump lol
eXp0N3nT1aL hey how much was the swap. I just bought a Fairmont and I want to put a 351w and transmission I have laying around. I'm 16 and on a budget for how cheap you think I can do it. I have a mechanic shop on my dads business so I have tools
So if I want to do a 351w swap I’ll have to find and engine out of an older ford then? I see they make new 351w crates but I’m not sure. I have an 89 foxbody.
I’d go for the 86-96 F series trucks or E series vans as they are already efi, even though the intake won’t fit in a fox... you can also go with the older 78-85 but it’s carb...
Can be. Depends on what all you’re needing. I prefer getting the long block so you get everything including the front accessories. I use www.car-part.com For my engines. Gives you a listing of all local parts yards that have what you want.
What distributor did you use? I know MSD has that one specifically for 351w swap I have an 87 vert but I'm keeping it carbureted. I just didn't catch if EFI vs Carb made any difference with the distributor
That depends on what electronics you keep from the factory. If you have stock wiring from a 5.0 that has a factory connector with a TFI module then you can use a factory ford distributor. I got mine for 50$. Brand new from rockauto.com. Ford trucks in 90-91 (and some other years) that had a 351w came with a TFI module and are plug and play with 5.0 mustang wiring harness. If you go carb and take out all the wiring, you'll need something like an MSD dizzy for a 351w and 6AL.
B Stang Thanks I'm gonna try and use that Truck distributor since I am keeping all my factory wiring but running a carb. If that doesn't work I'll be dropping $280 on that MSD unit thanks for your help
Couldn't agree more! I'll have to upload a video of the finished product. I have an 87 Vert and I'm swapping out the bone stock 302 and fired C4 automatic for my world class t5 and a 351w.
It wasn't too bad. I used a Haynes manual and made sure I knew what year car the wiring harness cane out of. Used the Haynes manual for reference to make sure I got everything right.
+Logan Boos 302 ----headers will fit, but you'll probably have issues connecting them to a factory style foxbody exhaust for a 302. the deck height of the 351w is taller than the 302, so it'll be a bit off from where they should be with a 302...
+Nick P I agree. They were cheaper than a $300 plus dollar hood. Not everyone is a rockstar with tons of money. You should share the wealth with the rest of us.
Nick P How do you figure it's not safe? The factory k member has two spots that contact the frame rail when you bolt it in. The fact that I increased the distance between the frame rail and k member by 1.5 inches did nothing to effect the strength of integrity of the car. If you don't like it, then don't do it. I'm just showing what worked for me in my application with the budget I had. Running with no hood was not an option for me since I drive my car on the street 80% of the time.
Nick P I didn't have 100$ for this: lmr.com/item/MM-MMKM21S/79-04-Ford-Mustang-Half-Inch-K-Member-Spacers?gclid=CK7W0aetw8wCFZY1aQodOgQMcw So I opted for the cheaper solution. My car, my mods. Don't like it, GTFO.
Nick P As for the oil pan, that was only a temporary fix. No welder, and no money to take it to a shop. The solid drop mounts and spacing the k member down let the supercharger fit under the hood without modifying the bracket. Do some more research before you troll on my video that's just trying to help people.
CuriousTyrone Thats kind of a tough question... I swapped from a V6 auto car to a 351w 5 speed. I had to spend quite a bit on parts that that wouldn't of worked even for a 302. fuel lines, pump, fuel rails, all front engine accessories, transmission, driveshaft, and the engine along with all the efi electronics. I was right around 2-3k into it, but the car was only 800$ when I bought it. If you're swapping from a 302 to a 351 it would be cheaper.
I started with a V6 auto and went to a supercharged 351w with a tko500 trans so what it cost me was a bit higher... I was around 4-5k on my setup. You could go cheaper and do a 351w with a t5 for 1500-2500 depending on your starting point. If you've already got a Foxbody that came with a t5 and 302, you'll have all the wiring and trans and it'll be real cheap.
I think that when I made this video, I still had a T5 manual transmission from around a 91 mustang. I have since switched to a TKO500, but have already outgrown that.
What fuel rails did you use to work with that lower intake? I have a similar intake and Made the mistake of getting 302 fuel rails witch had a different angle for the injectors and the mounting tabs didn’t line up at all.
When I bought the intake used, it came with an edelbrock fuel rail setup on it... I still have it laying around, but there’s no part number on it.. I would guess an edelbrock made for a 351w intake. Did you try summit racing or jegs?
I’ve looked on both and saw a few but wasn’t too sure if the tabs would line up to mount the rails down. On the link u put for the lower intake the pic shows the intake without the mounting points for the rails but noticed yours had them.
+Chuffing Ale lol I kinda thought you may be trying to grind my gears. I will say that Ford didn't necessarily make engine swaps an easy thing in Foxbody cars. Thanks for watching!
Dude that spacer bullshit is sketchy as fuck....all for a stock hood ...what a shit show. At least cut and drill steel plates that goes through both holes.
If I was that sketchy it would have failed some time in the last 10 years…. Yeah, super sketch. Used what I had to get it done at the time. Thanks for stopping by to throw some shade 🤘🏻🤘🏻🤘🏻
