Important Notes:
ABS
The ABS module was not in the video shopping list, but you will need it for cruise control to work in the 5.7L because they're a different part number from the 4.7L to 5.7L, otherwise cruise control will not work properly or at all. The ABS module part number you need is P52121407AB. The ABS module communicates the vehicle speed to the PCM and tire size can be programmed with the right scan tool to correct speedometer accuracy if needed. I did a video on that scan tool here: • Perfect scan tool for ...
PCM
The PCM part number you will need is P56029161AB (other part numbers work but with programming changes I’ll cover in a follow-up video). The PCM sets cruise control but requires input from the ABS module to function correctly. These two must work together.
SKIM
If you have SKIM, just delete it. You won’t be able to write your original 4.7L VIN to your 5.7L PCM (which is needed to match the unprogrammable ROM of the SKIM module) because it will trip the ABS and Brake lights with the “VIN Mismatch” code. So if you have SKIM, permanently remove the module before putting in the new PCM. Only 5.7L ABS modules will work with 5.7L VINs without tripping the code. I suspect this is due to the 8th-digit “D” in a 5.7L VIN vs. the “N” in a 4.7L VIN.
WIRE DIAGRAMS - drive.google.c...
Big thanks to my friends Liam and Nick for giving me a hand taking things apart and teaching me how to weld, and to my parents for giving me the space to work.
I have personally done several projects with this guy, he’s an absolute genius. Amazing quality video as well!
You came in clutch on a couple of those! Always fun working with you Sir 🤝
Plan on doing this when my 4.7 blows thank you
Cool! No problem
Thanks, man! You answered a lot of the unknowns. Especially the cruise control. Great job! I can tell you'll make a great doc!
Thanks! The book I used is just the wire diagrams and it’s linked in the description. You should be able to download it from there. I hadn’t thought of making lego instructions to do the swap but I might very well do it!
@Jonathan-Vasquez I'm working on a torsion bar delete for the 02 to 05 ram 1500's. Basically reinforcing front shock mounts to enable strut placement, therefore eliminating the torsion bar.
Is the goal to bulk up the suspension?
@Jonathan-Vasquez Basically, struts make working on front-end components much easier. Replacing a ball joint, for example, when struts are involved, easier. With torsion bars, those need to be removed. So, you have to mark the exact location of the bar to it's lock down point to ensure proper tension to achieve the proper ride height of the front of the truck. Or if you have to replace a front cv axle, the torsion bar needs to be removed first. It's really a pain in the ass. Also, if you wanted to do a suspension lift on your truck, there are more options for that with struts, while still retaining ride quality
They have kits to do a torsion bar to strut conversion for chevy trucks, but nothing for Dodge trucks.
I’ve removed both of my CV axles without messing with the torsion bars. It was pretty easy. I don’t believe they need to be messed with when doing the ball joints either, at least not in my experience. So that’s interesting 🤔
I think it’s awesome the torsion bars can be so easily adjusted to change the ride height of the front end and I think it was designed that way to account for different weight of the front end with varying engine sizes and 2WD/4WD options. After the swap, I turned the adjusters for the torsion bars to raise the front end 1.5 inches. Hemi weighs more.
I agree on the lifting limit though. The stock torsion keys limit lift in the front end while keeping ride comfort and I’ve read about the lack of aftermarket options for Dodge with torsion bar kits. Cool that you’re working on a solution for it 🫡
Nice job. I would liked to seen this in a series of videos. And more of a step by step.
This point has been made several times so I’m working on something for step-by-step. It will be a bit before I get something better put together but it’s in the works
The 4.7 is a great motor and reliable as long as you keep up maintenance. You can make the 4.7 have around 300hp for under 1000 if you get the upgraded cams, 08 intake manifold(make your own adapter if smart enough for old TB), remove motor fan clutch, port the throttle body, full catback with high flow cat and a superchips tune on 93 octane.
My opinion is that the 4.7 is good until it’s put it under load. Merging onto the highway, big hills, or pulling my trailer (2,500lbs unloaded) often required the pedal floored, which was not a fun feeling. To be fair, I also always had several hundred pounds of equipment on the truck as well which didn’t help. In a world without 5.7’s I’d be okay with the 4.7-never had mechanical problems with it for several years-but I’m very happy so far with the 5.7 345/375 HP/torque
But thanks for sharing a way to gain HP in the 4.7 too
@@Jonathan-Vasquez Yeah the 4.7 isnt fast by any means but I use it in my durango for light towing with a trailer(under 3k pounds) and going on family trips loaded with crap lol. Like you said the only down side is it sucks on top end bad. From a dig it takes off like crazy up till like 4k rpms. But I must say the 4.7 gets great gas mileage on the highway 21 ish.
That’s true, 4.7 gets better mileage. If I’m going 65mph or less I get 17.8mpg with the 5.7, calculated over a 271 mile trip and +/- some based on terrain. This is with the truck weighing in at about 7,650lbs, roughly 1k lbs over its unloaded factory weight. But above 65mph it’s lower and stop-and-go around town it’s more like 10mpg. That’s definitely lower than what I was getting in the 4.7 which I remember to be 13mpg. Durangos are about 1500 lbs lighter than a quad-cab truck so I’m sure it feels a lot faster than I experienced too. They probably feel pretty quick in single cab trucks as well
Great video, glad I found this. I have a 2004 Ram 1500 quad cab I got cheap from a friend with a high mileage 4.7 (283k miles). It’s still very reliable but very slow… I want to swap the engine for a 5.7, 6.1, or 6.4 once the engine dies cause the truck has a perfect interior and exterior has good original paint, so I feel it’s worth keeping.
Thanks, glad the video helps. 5.7 is the easiest to do, for the other engines you’ll need the transmission too. My opinion on the 1500 is that a 5.7 balances mileage and power pretty well. It’s up to you though.
Thanks for the feedback!
Brother…you have given me an insight on my 5.7,..I thank you for your service
Thanks for making this!
I’m in the process of planning to do a similar swap on my 2000 grand Cherokee. Similar to you, I’m not a professional mechanic (I’m a CPA). Cool to see other people with side quest skills.
Absolutely! Awesome to hear that from a CPA. I have a couple friends that are about to be CPAs and have a lot of respect for them
Good choice got a 2008 1500 with the 5.7 love it wouldn’t trade it for the world would probably find another motor used when it blows but 240k still doing pretty solid
Agreed! I’ve enjoyed the 5.7 every time I’ve driven it. I plan to drive it till it dies and then just fix it again like you said
hey commented before, this vid helped me so much with my LS swap thanks alot man. I've got a quick question though: i originally had the hemi and swapped to the ls, I want to get rid of the hemi's engine & trans harness only while leaving the body stuff alone and ABS, AC and all that, is that possible with the hemi harness? i know the two passenger computers are the PCM and TCM and the body module is connected to the fusebox but, some of the wiring like washer, headlights, etc in connector C100 (right above tcm and pcm) looks connected to it. Unless im wrong and it runs to connector C130 (driver side connector) which also has engine and trans wiring running to that. Also i know that the ABS, AC, and fuel level sensor runs to the pcm. Basically what im asking is if i just remove all engine wiring that goes to the tcm and pcm wiring and all that goes to c130 would the BCM and ABS and other stuff still function? Thanks.
Oh boy... that's a tough one. I know the section of the harness that's on top of the engine (2:50 running to the coils and spark plugs and such) can be removed because it disconnects at the two plugs beside/behind the throttle body. Any of the wiring can be run manually using the wire diagrams but in terms of separating the harness... eh... equally tedious. The harness is pretty well integrated so if you've got it running right, it may be more trouble than it's worth to remove the rest of the harness.
How did the LS swap integrate with all of the 3rd Gen Dodge systems? Or did it not integrate and that's why you're asking? I've heard about LS swaps from several people but don't know much about them.
@@Jonathan-Vasquez The LS swap works great, got the fuel wired to the Dodges stock pump, working on gauges and starter wire but other than that its perfect, its just that the hemi harness is just there in the engine bay in the way of everything, wanted to get it out lol. And yeah looking at it more and more it looks like a pain to get everything out, might just cut off the part that runs into the engine bay and leave everything else alone.
I have a 2007 I put a 2003 5.7l in. Computer, engine harness, chassis harness all plugged up. mounted up to the transmission without any problems connectors too. With all the stuff you mentioned as well. Truck will crank when jumping starter motor. but With key in ignition no lights no accessory only mileage shows up. When turn to run nothing.
Since the 2007 and 2003 are a different generation (3 and 3.5) the dash harness is likely different and the wiring to the starter may be different.
The best swap components for a 2007 would be 2006-2009. For my 2004 it would be 2004-2005 with the least effort, and 2002-2003 with some tweaking.
I’m not sure if I’m reading this correctly, did you use a 2007 engine harness and PCM with a 2003 engine? Or all 3 components from 2003?
The battery in my truck was low on charge so when I went to start it the next morning it wouldn’t start after starting it the first couple of times the night before. It just needed a jump and to run for a while for a good recharge. My gauge cluster wasn’t showing anything except the mileage when it was dead so that sounds similar. Hope you got it up and running.
3:24 - please tell me you took the DR headlight assembly too :) That was CLEAN!
If you’re referring to the scrapyard clip, I actually left everything there. I was just there to learn. Someone got a “free” engine though because when I came back several months later it was gone. Small-scale destiny
That's freaking awesome I want to do the same with my 2008 4.7 to a 5.7
Do you try it is that work for you
I have a 2007 Dodge Ram 1500 with a 4.7 and have found a 2008 with a 5.7. I am considering taking the 5.7 engine and transmission and putting them in the 2007. After what you have done could everything be done with out removeing and harness wires from the engine and transmission. And do you thing the mouts would match. also where did youdo your research on the swap before you this.
Breat job.
That should go pretty well. You’ll definitely have to move wiring from the ‘08 to the ‘07 but it should plug right into C219 on the dash side just like I did with mine. The motor mounts shouldn’t be the same so you’ll want to move those from the ‘08 to the ‘07 as well, which is pretty easy once the engine is out. Check out the comparison in my video where it shows how close they are but won’t fit quite right. All of my research was composed of:
1) lots and lots and lots of googling
2) the dodge forums
3) the wire diagrams I have linked in the description
4) visiting the scrapyard and taking things apart
Hope this helps and thanks!
very impressive!
Thanks! 👨🏻🔧
Now I want do this to my truck. I'm already having problems with my 4.7
My 2011 4.7 has almost 300k
@lavarunner5057 Damm, that's alot. I've been taking good care of my 4.7 but I think the dude before me skimped out on basic maintenance.
My 04 4.7 is at 283k miles. Engine is getting tired but still very reliable.
Since this is fairly new post believe it or not you do not need any extra wiring or anything the 4.7 pcm and harness will run and plug straight in to the 5.7 hemi with a few modifications to the throttle body as in manual throttle body hope to hear from you soon
This is technically true, but with some issues. I once read about someone in Germany running a 5.7 off a 4.7 setup like you’re saying but the issue was the programming for the crankshaft and camshaft timing was incorrect (and maybe some other sensors). You may be able to flash a 4.7 PCM with 5.7 programming (maybe) but to get everything to work properly and run any additional/different wiring correctly is very difficult. It can be done, and I considered doing it, but with 5.7 harnesses available at a scrapyard for $50 and a couple hours time, the minimization of variables that could go wrong is 100% worth it. It would cost significantly more time to be sure all the wiring is good if you use a modified 4.7 wiring setup.
I also wanted to keep my truck completely stock to retain its value. My engine may not match the VIN on the door, but the build is a stock build
Systems can be modified and implemented like you’re saying for sure though. I got rid of my manual 4x4 shifter and installed the electronic 4x4 dial switch (switch, module, wiring, and transfer case) simply to give me the footspace on the floor because I make long drives. Like this hemi swap, there was no clear documentation on the internet on how to. I just used the wire diagrams and traced the wires on a scrapyard truck to map it out and do the install. $300 worth of parts and I’m loving it.
If you get a 5.7 working properly on a 4.7 harness, definitely document it and share it on youtube! People will be impressed and enjoy it
@@Jonathan-Vasquez that is where you are 50% correct I ran it with the 4.7 pcm and wiring while I waited to go to the junkyard to get the right 5.7 harness and computer and it ran fine no additional programming or anything just hooked the pedal to a ghetto manual 5.7 throttle body me and my buddy fabricated didn’t have any issues other than it probably wasn’t being ran efficiently and fueling might’ve not been proper and it’ll work fine until whoever is doing the swap has enough money or whatever to get the pcm and harness
Great job then!
@@Jonathan-Vasquez yeah it was experimental I plugged in all the sensors and everything and it somehow worked and I was like well this works and I drove the truck for a little while like that
BR0 might just be a life saver for me
Good to hear!
@@Jonathan-Vasquez 4.7 head blew and i been wanting to do this but really didnt know what i had to get and replace
Me too on the wanting to do it for a long time. I wanted to for 5 years and finally decided to go for it. I learned what all I needed to do at the scrapyard on a junk truck and seriously did my homework. I didn’t know for sure it would all work out because I didn’t have a video like this to reference which is why I made it! It’s a good list of parts you’ll need but once you have them it’s 100% possible and very rewarding
There seems to be a lot of unclear info out there on this 4.7-5.7 swap for 3rd gens so this clears things up and I bet a lot of people in similar situations will be a bit more confident putting out the time/money to do it knowing it will work
Great video.. Will this same setup work with the 4.7 V8 2004 Jeep Grand Cherokee? I may have to hit you up in the future
I would imagine it’s similar but am honestly not sure
i have question how did cost you to buy 5.7 hemi at junkyard cause i want it
I got my 5.7 for $1,500 from a guy whose truck was t-boned. I got to see it run before buying and it only had 94,000 miles. That was through Facebook Marketplace. At the full-service junkyards they were selling for almost $3000 or more in some cases. I was quoted $2,800 by another shop. These were used at about 130,000 miles.
If you pull one from a junkyard yourself it will normally cost you $500-$1000 but remember: there’s a reason it’s in the junkyard. It could be damaged.
If you can’t find a good running one like I did, there is also eBay ($2000ish) or remanufactured ($5000+). Do some looking around. You can probably find a deal!
@@Jonathan-Vasquez ok thx
So how easy would it be to put a 5.7 from an 03 to a 02 with a 4.7
I think it would be very similar to this one I did. Make sure your wiring and engine are both set up the same in terms of EGR.
I will have the 10k mile update video published withing 1-2 weeks, possibly sooner, which will have some important explanations. I also plan on doing an in-depth 4.7 engine removal broken into multiple parts. All of these will be added to the hemi swap playlist
@ so I wrecked my 03 5.7 and I found a roller of an 02 4.7 so I mean I’d have everything
Then yes, it should be very straightforward since you’ve got everything. There really shouldn’t be much or any figuring things out, it’ll just be a lot of work. It can be done in a week, more or less based on experience. If you come across questions, I’m sure I can help. Go for it!
@@Jonathan-Vasquez you got instagram so I could just message you directly
I don’t, but my email is jrvsyt@gmail.com
Was the fuel system all the same ? i’m currently doing the swap
Yes, except for the segment of stainless steel fuel line and EVAP hose that run up over the back of the engine which plugs into the fuel rail and EVAP purge valve, respectively. It’s shaped different to accomodate the 5.7 shape and size. I show them in the video. Otherwise, same fuel system
@ Thank you so much sir. i’ll be coming to you again i’m sure lol
Question how much you think you would’ve been charge if you went to a mechanic
Some unbelievable amount, I’m sure. A normal labor rate is around $100/hr, multiplied by my rough estimate of 60 hrs I spent that week it’s $6000 in labor alone. And there would have to be time figuring it out since it isn’t a standard job. Rather then just replacing a part, they’re re-installiing almost all of the exterior electrical and having to make sure it functions correctly.
(Some mechanics please chime in here!)
@@Jonathan-Vasquezokay I got a 2002 doge ram 1500 magnum 3.7 single cab short bed and I went to junkyard pulled out a 2005 doge Dakota 4 door quad cab slt rwd SB got my old one out took flywheel off the new one went to trans to if it will line spun it around the torque converter to see if it lines up but it's an inch off the holes so I took both flywheels spun it around on the ground something I'm stuck don't know what to do everything else lined up and will plug in but the fly wheel I need help please please please bills are do no job and it's all I got and I don't have anyone to help me I don't run around the people I use to change of life
They use a different transmission so you’ll need a transmission as well. This is why I stressed making sure compatability was good
@@Jonathan-Vasquez the plat that goes in-between trans and engine line up perfectly i was thinking about going to auto parts store see if I can get a flywheel that will line but okay I thank you bud have a blessed day or night
@@Jonathan-Vasquez o and the plugs are different on trans is different than mine the Dakota are bigger than the one on mine
Did you have any problems with the pcm and skim security?
You can find info on SKIM in the description. I wrote more about it replying to a comment on my Launch scan tool video too. Hope this helps!
Hello there, I have a 2003 scsb with the 4.7, it’s probably an ok motor to rebuild but I would really rather have the 5.7 punch. Do you think I would have the best luck finding a 2003 with a 5.7 and using it as my donor? Or am I able to use any 3rd gen 5.7? I was looking into Holley terminator X as they claim to be able to run everything by just tuning the Holley… any feedback would be greatly appreciated
Putting a 5.7 in a single cab short bed will really give it some punch, so I would definitely take the upgrade route over a rebuild since you’re already doing all of the work taking the engine out. You can use any 3rd gen 5.7 but you’ll want to make sure it either has EGR or doesn’t and that it matches the wire harness and PCM in that regard. Otherwise you’ll get a permanent CEL or will have to delete the EGR with a block off plate to prevent matchup issues. I would definitely stick with a wire harness from your 2003 year if possible because some of the plug shapes change (ex. 2 of the plugs under the fuse box are shaped differently from ‘03 down and from 04’ up). I am also a huge proponent of keeping big things stock because stock was engineered by professionals, you have access to published pin outs of everything in the wiring, and it won’t harm the truck’s value. But if you’re considering swapping a different kind of motor or control system I honestly have no experience there. The wire harnesses are significantly different between the 4.7 and 5.7 so just changing an ECU wouldn’t be enough if that’s what you’re asking. You’ll want a 5.7 wire harness and whatever ECU you choose after that is up to you.
@ thanks for the information ✊🏽
Do you still have the whole wire harness? I think I need it.
For the 4.7? I kept it for several months but eventually tossed it while clearing out clutter
@@Jonathan-Vasquez Yep 4.7. I have 04 with a trashed hemi and a 4.7 on hand. Trying to figure out if it is feasible and economical. I have a buyer for the 04 and I would very much want him to buy the truck if you know what I mean.
Ah, ok. It would be easier for the buyer to replace the 5.7 than to swap to a 4.7, decreasing power decreases market value as well. But it depends on the condition of the rest of the truck
I recently got a 02 1500 with the 4.7 v8. I thought about doing this swap as well but mine has the 5 speed stick shift gearbox i would like to keep on the swap. Still possible with an updated 5.7?
It should definitely be possible. If you can find a wire harness from a truck with a manual transmission and a 5.7, you’re all set. Otherwise there would be some digging into wire diagrams to modify the harness from an automatic to work with the manual. The first option is the best, but they are probably very hard to find
@ couldnt i just trick the computer into thinking its always in neutral like some manual swaps are done
I honestly don’t know. But if you figure it out please post it here so others can read into it
I have a 2004 4.7 i wanna swap it with a 5.7 will my 4.7 transmission fit on the 5.7 motor thanks!
It’s the same transmission. All the information you’ll need to do your ‘04 is covered in the video & video description. Should turn out awesome!
How did you hook up the gas pedal to the 57 with it being electrical instead of cabled
16:23-17:29 shows it. There is still a cable attached to the throttle pedal but instead of running to the throttle body, for the 5.7 it runs to the TPS which is located underneath the battery box. The 4.7 and 5.7 cables goes through the firewall at the same place (next to the brake master cylinder)
^this is for 2004 and down. For 2005 and up, there is no throttle pedal cable at all for the 5.7 and instead a small wire harness runs through the firewall from the pedal to elsewhere. I can email a picture of that to you if needed.
@@Jonathan-Vasquez so for me to do this swap into a 2002 Dodge ram 1500. I would need a 03 or 04 parts truck.
I recommend sticking to your year. There are plug differences you’ll run into for certain years (ex. two of the plugs under the fuse box are different from 2003 down and 2004 up). You can use any year parts truck but you’ll likely find yourself swapping more things than I did in this video.
@ well the 2002 was the first year. They came out with that body style. It didn’t have the 57 hemi option so I was gonna get a wiring harness and all the other stuff I need for like a 2003 and it should work I know it’s possible I was just trying to find out a few more steps from you and you help me out thanks
Can you do this for a v6 ?
I expect it to be similar but don’t know the exact details. Make sure to check the transmission matches. I would imagine the dash harness to be the same too so I wouldn’t think it would be much different than what I did here
@ I’m not sure about the transmission because regardless I would be swapping it to that 545. Thank you for the response though !
By far the best video explaining the swap I have found
So did you hook up the 57 to the same 47 transmission?
Yep
I got a 2004 single cab ram with 3.7 v6 how would it be for my swap
I would expect it to be very similar to how mine went as long as you work with parts from the same year. You will probably also need a transmission
Quick question, the two big connectors you said they're the same right? Would it work if i swapped a 4.7 into a 5.7 using the 4.7 harness? cant find a hemi and need it running. I would just have to change the pcm
The harnesses are very different. You’d have a lot of careful re-wiring to do. The 5.7 has the engine bay harnesses separated into two: one directly on top of the engine and the other kind of around the engine plugging together at the two points next to the intake manifold behind (and driver’s side to) the throttle body. The 4.7 doesn’t use this 2-part harness. The 4.7 engine bay harness goes straight to everything. Better switching them out and avoiding potential electrical problems attempting to re-wire
@Jonathan-Vasquez Damn that sucks, cant find a hemi by me at all, might as well LS swap it, thanks.
Good job
I'm getting ready to do the swap in my 05 . i found and 05 hemi so it maybe a little easier maybe lol
Awesome! The 05 should be pretty much the exact same thing I did but possibly different part numbers for the ABS and PCM. I’m pretty confident I’ve figured everything out now and will be doing a 10k mile follow up video sometime soon. Will definitely include a couple different ways to get the cruise control working too!
I realize my video really skips over a lot of disassembly and reassembly details, so I hope to get a full-blown step-by-step published. Step-by-step was never my intent here, I really just wanted to include the key steps and show it could be done somewhat easily. I figure, anyone can google taking out a radiator, battery, intake resonator etc. hope my vid helps you out though!
I just remembered, I think the 05 uses a throttle pedal with the throttle position sensor right at the top of the pedal rather than running a cable to it under the battery and through the firewall. Just a heads up
My truck doesn't have abs brakes the throttle has just a wiring going to it I'm still in the doing my homework chapter but you video is very helpful
That’s intereting, it should have ABS at least in the rears so there should still be a module for it located behind the battery box. between the battery and the firewall. I would definitely expect ABS to be standard in 05 but let us know what you find
I might even take the opportunity to add ABS in the front if I were you. Always good for stopping in sudden situations
Hi man...i have 2009 grand cherokee 4.7 i wona swap to 5.7 hemi what i need to do ...thanks
I don’t know. It’s probably very similar but you’ll have to do the research. My schedule is booked. Good luck!
so my 07 dodge has a v6 will the wiring harness connect the same to the inside of the vehicle?
I don’t know but you can find out by checking wire diagrams or physical comparison to a hemi of that year
Does the transmission of the 4.7 fits the 5.7 engine? Mine is a 2007
I’m 99% sure the answer is yes
Also, i saw you made a knowledge book on your swap. Do have that available for download ? I would gladly pay you for that.
I’ll work on it and will keep you posted
@@Jonathan-Vasquez Thanks man.
Good job Jonathan.
Thanks Grandpa!
So when i go to the wrench a part and get a pcm do i need the immobilizer too? Confused how to program the key cant find any locksmith with software to reprogram ecu or pcu
Most PCMs from a scrapyard aren’t going to have SKIM equipped at all because SKIM was only used on the Laramie trim. Since mine is a Laramie and had a SKIM I got my 5.7 PCM’s VIN re-written with the VIN my truck came with (that is also in the SKIM) and then my keys automatically worked because the PCM and SKIM both showed the same VIN. Most locksmiths should be able to re-write a VIN because most scan tools over $1k do it. Locksmith shops usually have the fancy $3k+ ones. If they can program keys, their scanners can re-write the VIN in the PCM too. I’ve also used the Autel MS906 scanner to re-write my VIN. Hope this helps!
I would grab the PCM, SKIM, and ABS all from the same truck if you can because they’ll all show the same VIN, then all you have to do is reprogram your keys. That’s usually a few bucks at the locksmith
What fuse box did you use the 5.7 or can I use the 4.7 fuse box? Also can I remove the fuel and evap line without removing motor at the salvage yard?
I used my 4.7 fuse box, it’s identical.
Yes, you can pull the fuel & evap line without removing the engine. I pulled it over top of the driver side valve cover after taking the intake manifold off. There’s a little clip on the bellhousing with two bolts you can see in the video
When removing the cruise control module under the battery box it ties into a t. I have deleted it but the other end of the t goes into the firewall under the wiper cowl and I have researched and found it's called the vacuum reservoir. Did you delete yours or just change the t into a coupling going into the brake booster ?
Did you sell the 4.7
Yes, it was sold in August for $800 to a guy fixing up a truck to flip.
So wait did u use the 4.7 transmission or it don’t matter ?
Yes! The 4.7 and 5.7 transmission is the exact same hardware. They are called 45RFE and 545RFE, respectively, but are identical in construction. What changes is the programming such as the shift points when you plug in a different PCM. So, the 5.7 bolts right up to the transmission.
@@Jonathan-Vasquez thank you 🫡
@Jonathan-Vasquez 02s were 45s...from 03 on they were all 545s
What year is the motor?
2005
The 4.7 or the 5.7? I wanna swap my 02 but trying to figure out everything elts I need
@ I swapped a 2005 5.7 into the 2004 truck
this is so cool!
Will a 5.7 out of an 04 Durango work in a 04 ram 4.7
They should be identical engines except I’ve heard the starter motor is on the opposite side. You may need a Ram starter to account for the opposite shape
Didnt that generation come with the 5.7l hemi...?
Yes, 3rd gen 1500s came with several gas engine sizes. This one was a 4.7L
@@Jonathan-Vasquez interesting
@Jonathan-Vasquez they came with 5.9 gas and cummins diesels too
@@MidnightPolaris800 yeah the magnum v8 but honestly not a huge dodge guy i thought they stopped that with the 3rd gens, clearly not lol
Where are you located man 😂 can you do this for my truck please 🙏🏽
Different places at different times… I would be open to the possibility if you’re serious
@ I’m very serious
I have an email address in my channel bio. Send me an email and we can discuss it
@@Jonathan-Vasquez I’m having trouble finding the email

I’m something of a weird little red straight six pin myself
By far the funniest comment!! 🤣
Sweet!
Not only is it a power increase but also reliability upgrade. 4.7 are complete garbage and should be deleted from existence. Never have I seen a 4.7 truck for sale that didn’t need head gaskets or have overheating issues.
Because people don’t know how to manage the proper maintenance on em , you can easily find 4.7 at 300000+ miles while the hemi at 150k already has a wiped out cam
Agreed. My 4.7 never failed me in 5 years and I put it through good use. I think they’re solid engines, just lacking power for that size of truck and especially if you do consistent hauling. It goes both ways though. My Dad’s 5.7 has 220k on it and still runs like a dream. Maintenance and operation are key
The 4.7 is a sound engine for reliability if they aren’t abused and driven like a race car, and are well maintained the only thing that kills those engines are lack of maintenance and if you find a way to overheat them they hate it and that’s what the problem is with them never had a real problem with mine….but I did upgrade to a 1 ton 6.7 Cummins so the 4.7 is the backup now plus I’ve heard more complaints about the 5.7s than I’ve heard about the 3.7s & 4.7s except for them being a little sluggish
Complete garbage, yet dodge/jeep kept it for 14 years. Sure. 4k synthetic oil changes and service the cooling system every 5 years. Like saying the 42/44/46/47/48RE is garbage because you didn't read the owners manual stating service and adjust bands every 30k.
I bet this was a school project…
I don’t know of any pre-med degrees that require engine work or welding
@@Jonathan-Vasquez😂
hemi 👎 neice job, but no one will appreciate it. useless.
Ls loverboy 😂
