How to install a 4 6L crown vic engine into a mustang GT
HTML-код
- Опубликовано: 26 сен 2024
- Basic information on what you need to know on how to swap over a vic/grand marquis engine into a 99-04 GT. Some other modular 4.6L's will work from the V8 explorer, F150, Lincoln Town car, & Mercury Mountaineer depending on year however some components like the timing cover need to be transferred over. There are some things not mentioned in the video such as making sure not to use flexplate bolts on a flywheel because they are shorter and to use trans bolts from your 5 speed if you are taking an engine from an auto. Not everything can be explained and its always a good idea to use new gaskets and hardware. Flexplate bolts are torque to yield and shouldn't be reused. This video is to show the way to do it with some tips.

I am in the process of an identical task. I want to thank you. Extremely informative. Valuable information.
Thanks
It is a miracle my engine hasn't been completely destroyed. My timing chain tensioner completely failed and I jumped timing. Also I noticed the Utah plates, hopefully I see you on the road sometime.
I live in southern Utah. Seems like all the mustang people are up north.
What were the symptoms of the jumped timing?
@@brynden29 it just ran terribly. I caught it before it really got bad.
@@jaydenray2803 thanks. Do you think skipped timing would cause extremely low compression on both sides of the motor?
@@brynden29 it's possible. I would take off the valve covers and inspect the valves and see if the timing chain marks line up with the markings on the cam gear.
Thanks for the details. I plan on changing from a 3.8 to 4.6 someday.
Good information and videoed well with good description. I wish someone would do a 4v swap that detailed.
I was thinking about doing the same to my 2003 GT 2v. I would like to swap it for a 4v.
Thanks
thank you for all your info, igot a 2010 grand marquis engine with 98,000 miles, my mustang is running!!!
Awesome!
I agree that it is way cheaper to buy a junkyard engine that runs VS rebuilding one. My 01 Grand Marquis has a junkyard 4.6 engine in it from a wrecked 02 F150. The intake was swapped to fit in the GM engine bay/hood. She purrs good.
You just got a new subscriber man.. all this detail you've covered got me looking at my car differently ...you're the man
I appreciate your feedback. Thank you.
Lots of good info here. I have a Crown Vic and a Grand Marquis, and this will help me maintain both, and whatever tomfoolery I decided to throw at them.
For sure. The 4.6L had a very long and reliable run.
Hello Justin, today is Friday, June 16th, 2023. I have an update on my GT project. The car cranks, starts, runs and is in motion. Granted, I only moved the car from one extreme of my yard to another. The reason for this is to get the car under the car porch shaded area. Where it was originally parked I would say that it was there for almost two years. The car still lacks many connections here and there. Radiator needs installation. Power steering pump needs installation. AC Compressor needs installation. AC Condenser needs installation. Some vacuum lines need mending due to heat baking making them brittle. I need to shave down the bank one exhaust manifold due to it being very close to the steering shaft (it has a horn where the EGR breather was situated). I will take a Dremel pencil grinder to that area. The car has no tailpipe. This said, when It starts, it make a shitload of noise. But nice noise nonetheless. Oh, I am currently working on the tailpipe O2 sensor set-up. It is one big hassle in 'bank one', for the EGR breather line has to be situated to run up from the tail pipe, past the firewall and connect to the EGR valve. I have made some modifications to this snake-type breather line. But it is working properly. Let's see.....After I finish the EGR valves set up I'll move to properly connect the Vacuum Solenoid valve. I'll have to make some modifications to the bracket on this too. When I'm done with this, I'll move on to the Power-steering pump. I have no idea how to put this guy back in. I don't remember how I removed it. I will do research on youtube to get this guy properly back in. In all, thank you for your support. Happy Fathers Day 2023.
Good luck with all the work ahead. I hope it goes smoothly
The inside of my 2006 Crown Victoria Police Interceptor's engine is spotless even with 160,000 miles and 4000 idle hours and still runs strong and uses no oil.
I believe it. I’ve bought 2 from ex police cars and they were nice too
Yea, just did this with my sons 03 gt, and put an 05 crown vic moter in it and you will have to strip down the mustang motor to the heads and block and put all that, on the crown vic motor to make it work! We ended up with 4 totes of crown vic parts that had to be changed off an mustang motor parts put on the vic motor to make it work! I guess it's cheaper to do that, but do not let anybody say,( all you have to do is) cause you will find out all about that all you got to do bs! It is strip mustang motor to the block and heads, and put on vic motor to make it work! We know!!!!
Happy 4th of July Justin. Thank you for all the advice. I'm really close to installing the engine and tranny into the Mustang GT. Thank you once again. I know it's been four months since the last time we spoke, but there was the process of rebuilding the tranny all by my lonesome. And then there are the mods on the engine that have to be done. Oil Filter housing needs work due to the sensor for one. And other little issues too. Have to clean the engine tranny bay. Fuel rail change. Throttle body/Plenum change. Well, you know the drill.
That’s great, good luck with the install
I did the same swap with a 2008 Lincoln motor. Timing cover was different I just had to use a different belt when I bolted up my A/C and power steering pump. Also reused the Lincoln’s oil filter housing. So far so good. Loving the low mile engine
That’s really cool. Good to know you can still use the Lincoln oil filter adapter if you have to. So the mustang hose still fits with it?
@@justin.c_svt Hi Justin...There's two people that I know of that shared their experiences regarding the swaps with crown vic engines... and apparently the oil filter adapter works just fine in both performance and no problems hooking up the lower rad hose. In your opinion is that even possible?
The angle the hose needs to attach isn’t off too far between the two adapters, but I would be hesitant that the hose could possibly kink or bend when heated coolant flows through it over time. I would think that ford made them different for a reason. The 4.6L 2V & 4V were both used in earlier Lincoln’s and ford cars since 91 and didn’t go into mustangs until 96. When ford chose to do that they obviously had to engineer that new oil filter adapter for the mustang for some reason. It might be perfectly fine but there may be a long term reason. If I had to do it over again and I didn’t have the mustang one, I might just reuse the Vic one since others have said it’s fine. You can never go wrong with putting exactly what the car came with on though.
@@justin.c_svt Justin, I appreciate the reply. I agree with you, if the Mustang Oil filter adapter is available then it should be used. If not available (hard to find sometimes) then the Vic's oil filter adapter might work fine.
From what I recall, GTs from 96-98 had a different oil filter adapter that had oil coolers built in. It wasn't until 1999 that the oil coolers were removed from the Mustang's oil adapter's design. The early GTs (96-98) oil adapters are round and has a snail like design.
I remember people with those early GTs switching over to the new design because the old ones with oil coolers liked to leak..
The 99-04 oil filter adapters look like both shown in this video and if you compare the Vic's to the Newedge's, they are similar in design (no oil cooler version).
Thank you again, Justin. You are an inspiration to many people including myself.
@MustangFord Thank you. I haven’t heard of the earlier 95-98 GT’s having the oil coolers, but I know the cobras have them. My terminator cobras have them, and my 98 cobra had one too, but funny enough the Mach 1’s didn’t get them even though they are 4V’s. I believe the crown Vic police cars got them saw well.
Hello, Justin, I'll try to keep it short. As of today, April 8th, 2023, the engine and tranny have been installed. Tranny has drive shaft installed too. Just need to double-check and triple check all bolts and stuff. The engine cranks and starts. Granted, it is missing many sensor being connected and the EGR valve connected making for the engine to hesitate somewhat. But it does start and rev. When I have the engine running well I'll move the GT to the shaded area of my residence and continue installing the rest of the stuff: AC stuff, radiator, tranny cooler. By then I'll be almost done. Thank you for all the advice. Happy Easter 2023.
That’s great. Happy Easter too. Thanks
ladies and gentlemen, danny johnsons brother
The first 4.6l 2v and the 5.0l 4v were originally in Lincoln's, just a fun fact.
I have a 2003 Crown vic engine in my Mustang and I cant even tell the difference between that engine and my old Mustang engine... As a matter of fact I am pretty sur the crown vic engine has more power to it ! But I also put it in long tube headers and new injectors. Got the crown vic engine for $600 Canadian ! I would do it again in a heart beat ! Almost dropped in an LS but somebody got it before me ! That would have been interesting ! And it was only $800 !
Very cool.
Great video Justin. Does make more sense to just replace the engine VS trying to rebuild it considering your going to be doing a lot of these steps regardless. Plus not having to deal with removing the heads and the timing and all of that in the case of a head gasket. Good thing these 2v engines care so plentiful and are so cheap, really does make these swaps more economical
Thanks! Yeah I hope many can watch this. Too bad cobra engines aren’t so easy to replace haha.
@@justin.c_svt That’s for sure lol! Hoping I never get to that point
Me too yet I know many who have or even my cousins Mach 1. It’s very pricy to fix
@@justin.c_svt it’s expensive enough as it is lol. Just working on making it reliable at the power level it’s at now without breaking stuff
Thank you for making this video.
🤙🏻
Just bought a 4.6 l out of a 04 Lincoln towncar hopefully works on my 02 mustang roush stage 2
It should
Great information Justin, I'm very pleased with knowledge from you and your brother with the New Edge Mustang s .I have a 2004 that I purchased from my son with a bad motor, so thank you for your videos.
Thank you. I hope you get it running soon.
Will long tube headers add much power to the 2valve engine & is worth the cost of adding them ? I'm big fan of you and your brother for the New Edge information any sites where I can purchase quality products?
They add more torque than anything else and change the curve of where the torque comes in. I’ve had bassani’s that were really good. One thing to keep in mind is that most long tubes get in the way of dropping the transmission so if your car is a manual than it’s harder to do a clutch. You might have to loosen the headers to get the trans down.
Great video definitely will help the people out there
Excellent, Excellent video content Justin. Thank you very very much to you SIR👍👍👍👍
I appreciate that. Thank you
Very awesome video! Definitely helping in my project virtually the same except mine with the 5spd. I’m having trouble finding the correct pilot bearing though. Have a specific part number by chance
I don’t. There shouldn’t be any real difference.
I NEEDED DIS💯, good video bro
Thank you.
Is there any way to make other v8s sound like the 4.6 L 2v? The music those engines made was just unreal.
Just built a 4.6 haven't heard it fire yet sound nice
Good luck 👍🏻
Man I could really use your help i recenly swapped a 04 Grand Marquis motor with 44,000 miles into my 99 Mustang Gt I heard this motor run before pulling it and it ran flawlessly. I actually watched this video prior to the doing the install. I swapped the oil pickup, oil filter housing, etc, I noticed that the location of the idler and tensioner were a little different than my original motor but figured it wouldn't make much of a difference besides having to use a different belt of course. I also reused my old intake and injectors(all new gaskets and o rings) I put all new injectors, ignition coils, sparks plugs,maf, iat sensor. Well we try to start it and we get a flashing theft light with no crank well apparently I wasn't paying attention and I grounded out the little radio noice supressor mounted on the head on the front of the motor and it blew my pcm maxi fuse(not sure if It could have maybe went farther than that?) Well i replace it we crank it and it starts up almost instantly but at idle the rpm is jumping all over the place its missing and runs really bad but if you hold it at 3k rmp or give it gas it clears up completely until it comes back down to idle car smells of raw fuel out of the driver side tailpipe so I belive its dumping extra fuel I just can't figure out why only code I have that stuck is my b1s2 which i replaced. And had a ignition coil e (cylinder 5) code but I confirmed that the coil is firing. I know this is alot but if there's any advice or something you think I should try please let me know I would greatly appreciate it its been down for a long six months and I just want my car back
The timing cover on the 04 marquis engine I got was the same as my 03 GT but some of the pulleys were in different spots and needed to be swapped around then they were how it was on the GT. As for the running issues, it sounds like the computer is trying to compensate for false information. For example if you have a bad 02 sensor telling the computer wrong information, the computer will try and compensate with different ways like adding fuel, cutting fuel, advancing timing or whatever it thinks. So maybe a bad sensor or something and even a possibility of a wiring issue with the ECM failing. As for the engine, there shouldn’t be anything from the swap causing the issue. As far as the car knows, it still has the original engine in it because they are identical (besides the fact that the previous was made at the Windsor plant and has minor differences)
Did it work for your 99 ? I’m thinking about doing it to my 00 mustang gt but I see that it’s a different fly wheel and clutch on em
Regarding the exhaust manifold studs, do yourself a favor and upgrade to the stainless steel manifold studs and never worry about snapped and rusted studs again.
I got the 04 mustang gt 4.6l v8 what’s motor should I put in mine the crown Victoria or the grand marquis
Justin, this video was awesome and great detail. In the reminder of things that need to be done was magnificent. I live in Texas right down the street from Texas motor speedway i’m looking at a Mustang 5.0 that needs an engine. It’s a automatic Fox Body 1992 if I need help, can I ask you for questions in 10 A crown Vic or Marquis motor go in there ???
Swapping one into a fox body would be difficult.
I got a 4.6 out of Grand Marquis 2005 in put in my 2001 mustang GT and it works fine I didn't no it would work
👍🏻
Great video .. thanks a lot for sharing. Regarding the wire harness? What did you end up doing ? And does all your gages work?
The wiring harness stays in the car. If you get one from the crown Vic engine then get rid of it
Great video Justin! Thanks for sharing your knowledge and experience. My '94 Stang is a good candidate for a Crown Vic 4.6L from its original V6. Are there any major issues with using a newer 4.6L donor?
There are a lot of things that need to be changed. There are write up about it all on the forums
My grand Marquis gets treated like a Honda Civic. She loves it 😂 I haven't lost to a mustang yet. And I don't dump $ in it and never had the engine apart AND stock 2.73:1 gears 😂 who needs a mustang when you can be incognito, comfortable, and have company on a nice drive? 😂 Mustang guys
Awesome video well appreciated
Thanks
Awesome video very informational 🙏
Thank you

Is it the same process for a 94-97 third lx?
I got the idea of buying a used engine but with all do respect I will do that the way if I got a regular GT. But, I have a Bullitt and I think the car deserves a good crate engine and transmission. An I’m looking for a good reputable shop in NJ.
The bullitts engine is the same as any Vic engine. Made in the same assembly line at the same time
@@justin.c_svt I was inspecting the car this weekend and I found out that when the noise/knocking/metal to metal come on and I top at the catalytic converter the noise when away maybe because there is a peck right after the CAT. But when it happened the second time the tapping didn’t work. I am checking two muscle cars shops in my area Advanced Auto Repair
Great video! Could you do that to a 96 to 98 GT as well? With PI heads!
Yes. I did with a 97. The tune will be a little off so I don’t recommend racing it around without a tune
@@justin.c_svt got ya
do you know what the suspension set up was on that silver GT was? Looks sweet.
I have a 2000 gt automatic, im swapping a 06 grand marquis engine in it what do i do about the flexplate and torque
Use the one from the mustang
I've watched this video many times as I'm preparing to do a very similar swap, my question if you don't mind is how did you get the coolant tube from the valley off? I have the motor loose, and everything is ready, I'm having a hell of a time getting the transmission (5 Speed) to come off the motor so I'm just going to re-bolt it back on and just get a load leveler and pull it all as one unit. I found a motor out of a grand marquis that is out of 2007 so I'm hoping that the timing cover is the same because the reason I'm even doing the swap is my original motor shredded its timing cover with chain slap. Any idea if the grand marquis timing cover is the same as on a 2002 Romeo 4.6? Thanks man you're awesome for doing this video! Subbed for sure!
I believe that’s the right cover. I did one off an 07 or 09 I believe and it was the same as my 01 Romeo. Remember the 5 speed will require you to install a pilot bearing which is easy to pound in. Just don’t forget it. The coolant tube just twisted off easily in a back and forth motion. You can try spraying wd40 in it to help and I recommend replacing the o rings on the part the tube goes on when you are ready to install and lube the o rings so they don’t tear during installation
@@justin.c_svt thanks for the response! Also I'm an idiot I hadn't unbolted it from the block first and then like you said it just twisted right off. Lol
Oh good. Glad you got it
Can they fit in a 96 ford thunderbird
Great video man so in depth and informative. I have one quick question. I am swapping a PI Romeo motor into my 98 GT which originally had the 8 bolt crank Windsor motor. Do I need a new 6 bolt fly wheel and a whole new clutch or can I just get the 6 bolt fly wheel? I do have a new clutch in the car already
Some clutch kits specify the year and transmission. Yours would be a T45. If your clutch kit says it works with the T45 or TR3650 it should be ok. I’m pretty sure it would work. I’ve seen clutch kits for 96-04. Might just have to try it and see or ask on the Facebook pages
Thanks for the great video! I"m putting a 4.6 from a 95 cougar in my 95 t-bird. Supposedly has 40k miles on it. Seems believable from looking at it. I plan to do pan gasket and valve cover gaskets. Wat is your view on doing the valve stem seals at this point?
Just did this swap. Everything went smooth but, I forgot to put a pilot bearing 🤦🏾♂️🤦🏾♂️🤦🏾♂️ sound like somebody playing the drums 😂 should I be able to install one? I ain’t drive it much
I guess you’ll have to pull the transmission and find out.
So, I wouldn't be able to swap a 4.0 from the S197 to the P71 4.6 and use the T5 that came with the S197 4.0? Just a very serious question...
I am having a really hard time finding the specific pickup tube for my mustang. Can you post a link to kne that would work. Lmr/American muscle and cjpony parts dont have a pickup tube specifically for 99-04 4.6
I don’t know where you would find one. Did you try the ford dealership or rock auto? eBay may have one pop up.
Hey bro I was wondering could I use a p intake from a Mercury Mountaineer 2005 on my 2000 Mustang GT it looks the same the only reason why I wanted to go with this I cannot find a Ford Racing Pi intake replacement brand new anywhere all I'm finding is the opr brand which is Dorman and I'm trying to stay away from it I heard they upgraded them but I'm not sure don't want to end up losing 10 to 15 horsepower
I’m not sure if you can. I think you can on the Vic so it depends on how the plenum bolts on
What year crown Vic would I need to get to put into my manual 2002 mustang gt
2001 to 2011
I’m trying to put a Vic motor in my 96 gt (non pi) . Would I still follow the same steps? Thank u. Great video.
Yeah. There will be some differences like the ignition wires and the timing covers may be different ect
I know this is old, but I have an 03 Mustang gt. Very nice condition, I already put a t56 trans and aluminum drive shaft out of an 03 cobra in it. How difficult is it to swap a 32v into this car? Any info is appreciated.
It wouldn’t be much different, just need to get the wiring harness and computer and all that stuff in.
@@justin.c_svt I appreciate the info. Ty.
Thank you I have a 08 4.0 I want to swap to 4.6 so bad
I have a mustang 4.6, I wanna swap it for my crown Victoria 4.6 , is there anything major that needs done or is it pretty much plug and play
Did you watch the video?
Hey, great video. I just did this same swap with an 02 town car motor except I did it into a V6. Since I didn't have a gt motor with parts to swap, I kept the oil pan and pickup tube, and they seem to work just fine for now. Would it hurt to keep using the oil pickup tube and oil pan from the town car if I didn't change either of them, or do I need to find mustang ones? Thanks
If they are both from the Vic it should be fine
@@justin.c_svt okay cool thank you!
Did you change the transmission?
No it’s the same one that was in the car. I hear the Vic is the same but the flex plate and torque converter are different
Nice job. Sure is a lot of work though.
Should we change cam and timing chains? 2004 marquis to 2001 GT Bullitt. Are the valves and cams all the same in these two motors? Bought Bullitt for son and bent rod three hours later.
No. The cams, chains, and internals are all the same as the bullitt. I would only replace the chain guides and tensioners if they need to be replaced but if it is a nice engine they are probably fine.
Thank you Justin this is an incredibly informative video and I've been looking for this information when the day comes when I do it to mine
Thank you
Do you know what ill need to take off a crown vic that has the e85 fuel system
The fuel rail can’t be used anyway because it’s feed lines are different. Use the mustang fuel rails and injectors and it should be fine. I don’t believe the intake manifold or anything would be different. The E85 or flex fuel would most likely be the tune. Does it have yellow top injectors?
So if your Mustang has a 6 cylinder and you replace it with the 8 cylinder do you have to change the computer or wiring harness?
Yes, there is a lot to change. There are other RUclips videos and write ups on the forums about all that.
@@justin.c_svt I haven't been able to find it.
Can you use a 4.6 from an 09 flex fuel Vic?
That’s a good question. I think people in the comments said they have but you just have to make sure to keep your stock fuel system and injectors. The flex fuel or even natural gas cars have a different tune but that might be the only difference. You can google it
And should I get the gasoline or flex fuel engine?
Hopefully you can help me… so in a nutshell i have 99 new edge v6 that i am swapping & my grandmother has a 1994 grand marquis with a 4.6l in it, it belonged to my late grandfather who loved mustangs, low mileage & fairly well taken car of motor wise, but the body is trash, so my question is will this motor work? Im aware that its a non pi motor, but can’t i swap pi heads on or even do a 4v head swap? I just want to make sure it will fit on a t45 and if things will swap over & do you know what kind of block they had vs mustangs?
As far as I know yes the T45 will bolt up to any year 4.6L modular engine. A big factor in the swap
Will be what computer you choose to go with. 90’s mustangs will have ignition wires and 99+ will have the ignition coil setup. People have been known to put PI heads on the non-PI bottom ends to gain a little power because they actually have higher compression. You will have to decide to use or eliminate the PATS system and more.
@@justin.c_svt thats what i thought, but someone said on reddit that they had different bellhousing patterns on the block in 94-95 but just goes to show you cant trust everyone on reddit 😂 so i wanted to double check, and i have the full pats system from an 03 gt & a 99 gt wiring harness, can i not convert the older 4.6l to coils? If not i will just let it go & look for a pi motor
I think the older 4.6L can be used with the newer ignition coils. My friend put a non pi 4.6L from a town car in his 04 GT. It was down on power of course but it worked. As far as I know the older 4.6L has the same block and it should have the same bell housing pattern. The 93 mark 8 4V has the same block as the 96-98 cobra
Hey Justin will this work for my 2000 mustang ?
If it’s a GT then yes.
I just did a swap out of a 97 crown Vic into a 99 mustang gt and now can’t get fire, the motor had individual coils on front of each valve cover and swapped it all over to independent coils
Have a clue what could be wrong? Thanks in advance
The 97 is the wrong year. It’s an ignition wire non PI engine. You need a 2001 or newer Vic engine as explained in the video. You can still get it to run but it will be down on power
How did you get it to line up wit the converter im doing a crown Vic swap
Hello Justin, today is Saturday, July the 16th, 2022. I have run into a speed bump. Here you go. The passenger side motor mount on my 99 GT is factory. There is a galvanized thin plate that goes in between the motor mount and K-member. Or in other words, once you bolt down the engine with the K-Member this plate has to be in between these two. I don't know if this plate is a bracket for wiring or the transmission cooling lines. But I do know that it came from this motor mount. I would say this galvanized plate is about 5" X 6". My question, which way does this plate sit? Does it sit with the bend the plate has facing toward the engine or towards the K-Member. This galvanized plate has slot for the mount screw to easily slide in. It also has a notch just to the left of the motor mount screw. This notch also slips into a slot on the galvanized plate. This said, there is only two ways this plate can sit. But only one way is correct. But I revert to my first question. By the way, the transmission has already been rebuilt. It is also coupled with the engine. Plus, the torque converter has been properly secured to the flex plate. I also installed the starter yesterday and applied some power to the starter for a few seconds and the engine turned over. This said, we are getting close to installing the power train into the GT. Do you have a facebook account? Thank you for you advice. Keep up the good work.
Does this picture help? www.amazon.com/K1786-1999-2004-Mustang-Except-Cobra/dp/B06XDSZX25
@@justin.c_svt That Amazon link shows three items: two motor mounts and a what looks like a cross member bridge. The motor mount in the middle and far right is the one I'm talking about. On the mount itself sits a thin galvanized sheet. The sheet has two holes. One for the threaded mount bolt and the other for the notch lock. Anyway, I did some online research and found some picture illustration of a 3.6 or 3.8 liter Ford mustang and It shows this the galvanized sheet ears pointing towards the engine. This is the way I will install it. Thank you.
Yeah I was hoping the picture would show somewhat the orientation. I’m glad you were able to figure it out.
Have you ever had a problem with it getting fuel but no spark I have a 1998 4.6 put a crown Vic motor in it and no spark anything it could be
I can’t recall having that issue. Did you check all the grounds?
I have a 10’ interceptor in mine
Very nice. I believe the newest one I’ve had was an 09
@@justin.c_svt hey man, when you called the junk yard did you have to ask for a crown Vic motor or did they offer it? What year(s) would fit in a 2004 mustang GT? Thanks so much.
I already knew that any 4.6L from a Vic or marquis would work so I just went in person and asked to see any 01+ Vic engines. They said they had a marquis one and showed me that their system shows which engine had the same timing cover and other 4.6L’s they had that were similar but didn’t have the same timing cover
@@justin.c_svt thanks so much. My sons motor has extremely low compression on both sides of the engine. The plugs smell like gas so I know we’re getting fuel, and I pulled a spark plug and we are getting good spark. I did another compression test with a solid probe so I could screw it on farther. Drivers side: 15-5-0-15 passengers side: 75-30-30-65. We are taking off all the front of the motor so we can check the timing. Hopefully it jumped timing a little bit. I know it’s an interference motor so hopefully not too much. It sounds like you would recommend getting a new junkyard motor over taking the heads off and having them serviced? The motor has 159,000 miles on it.
Yes. Totally worth getting another engine. Head bolt kit and gaskets alone are like half the cost. Not to mention all the time and effort
I wouldn’t have to replace my transmission on my 2002 mustang v6 if put a p71 engine in correct?
I think you would. The trans and block bolts might not line up
Nice tang
Are people who have 99 and 2000 mustangs excluded from using Murcary grand marquis engines and Crown vic engines because these years of Mustangs were built by the Windsor factory and the 2001-2004 mustang engines were built by Romeo? Or just depending on the viechle the engine will be different.
No. A Romeo engine will fit just fine. My brothers GT had a Windsor and now it has a Romeo. You just might need to buy some parts to make it work like the flywheel because the bolt count is different and the valve covers. There are some long conversations about this with details in the comment section
@@justin.c_svt I greatly appreciate the reply. I was able to pick up a good Murcary grand marquis engine today and I'm getting ready to drop it in my mustang. Can't wait to drive it again.
It’s going in a 99-00 from what you said earlier I presume. Was the grand marque a 2001 or later?
@@justin.c_svt yes it was a 2006 Murcary grand marquis with 90k miles. We have to swap a few parts like a clutch and flywheel but I was going to replace those parts anyways. I'll post an update on how it goes.
@bluehairedlawyer8242 awesome
I have a 98 gt I’m putting a 08 police interceptor 4.6 in it
Cool. I put one in a 97 GT
I had seen you mention here in these comments replying to another fella that if my mustang came with a Windsor originally as opposed to a Romeo, the crank bolt count would be different. Would it be as easy as just purchasing the corresponding flywheel? Would anything else be different to the best of your knowledge?
Yes, you should be able to buy the correct number bolt flywheel or flex plate if it’s an automatic. If it’s a manual, add the pilot bearing like I mentioned. Other than that there really isn’t much difference besides the cam covers having a different bolt count and the possible timing cover difference and interior details that shouldn’t matter so much such as the cam gears being pressed on vs bolted on.
@@justin.c_svt I appreciate you taking time to reply man, you’ve been a great help
@KPotassiumK 👍🏻
I know I’m late, I’m swapping mine and my fly wheel has different bolt than the grandmarquis, is there one that will fit for a manual
Does your flywheel have 8 bolts?
Are the toque converter bolts supposed to line up with flywheel I have mine in but the bolts aren't lined up
Do you have the correct flexplate (flywheel) the Vic is different than the mustang and so is the converter
I’m putting a crown Vic engine into my 96 gt. The timing cover is different.
I put one in my 97 and it still worked
My 04 snaps the timing chain guides...you think is worth it replace them or just swap another engine on it????
Depends on if it damaged anything. Chains ok? Did it skip time and bend any valves?
So I’m swapping a crown Vic engine into a 3.8, why are you suggesting swapping over so much stuff if they’re identical? Then again the engine I’m getting comes full dress and is an npi
You have to swap the mustang specific piece over.
Hey I have a 1996 mustang gt 4.6l v8, has bad rod knock got metal shaving in my oil. What’s the best crown Vic year to swap with? And all I need. To replace is oil pan, oil pick up tube, exhaust manifolds, intake plenum?, obviously motor mounts and how about wiring harness do I need to swap that with the mustang one? My bad first time swapping so I just wanna make sure😂
Keep you wiring harness. Try to get the 4.6 that’s about the same year as yours. I put a newer one in my 97 (from an 05) and it was nice with some power improvements
@@justin.c_svtok cool so keep the stock crown Vic one? Or mustang harness?
@WhosThatRedPrelude keep your mustang harness
@@justin.c_svtquick question, I swapped my mustang but sent it and just swapped out the plenum nothing else n blew I again💀 my fault that’s cause I dented the oil pan, can I just swap out the oil pan and plenum and be good you think?
Did you swap out the oil pan and the oil pickup tube inside the pan? That’s the more critical part.
Can a flex fuel engine be used?
I’m not sure.
Can you use same flywheel from crownvic to attach to manual transmission
No. It’s it doesn’t have a flywheel it has a flex plate and it is different than the mustang flex plate as well.
Please excuse my ignorance. As a mechanic, I'm a decent woodworker. Is there any problem changing the oil fill from one valve cover to the other?
No, just make sure you dont have a fill valve cover on each side. My friend had one on each side and it gave him vacuum issues.
@@justin.c_svt Looking to put a set of Trick Flow covers on, oil fill on passenger side because the zip tube for the 09 P71 airbox I'm upgrading to blocks the stock oil fill location. Who wants to take the zip tube off just to add oil? Oh, yeah. 2000 Grand Marquis. One sweet ride!
Thanks.
@@johngregory4801 I understand that. The bullitt is the only new edge that has the oil filler on the driver side because of the intake manifold. I had a set of BBK tall aluminum valve covers and the oil filler neck was on the passenger side because they were PI covers and it wouldnt clear the bullitt intake so I went back to stock.
Question? Why did u pull out the knock sensor and leave a hole into the engine where the valley gets really dirty..wouldn't stuff fall in that hole right into the engine?
All the GT's have the same hole there. I was more concerned of it interfering with the intake manifold although now that I know they are interchangeable thats probably not the case. Another reason is because I sold the car and I didnt want the new owner to wonder why there were unplugged harnesses or sensors under there if he looked around.
@@justin.c_svtoic..gotcha! ty 👍
can i put a mustang gt engine in my grand marquis will it make more power i will prop swap the computer because the tune is probaly different
Yes you can swap it over but it will not make more power. The engines are completely identical the only reason why the Vic mix less power is because of its air intake, exhaust, and factory tune that’s less aggressive
@@justin.c_svt ok i understand ill just swap the pcm then to get a better tune and also the intake manifolds
Why swap the pcm?
@@justin.c_svt sorry i mean ecu so i can have the mustang tune on the crown vic
It probably won’t run with that ecu. The gauge cluster and key have to match the ecu to run and the whole wire harness is different. You just need to get a tune for the marquis
I just fired mines up and start right up but I get smoke coming from the left side passenger header, any thing it can be?
Also the throttle is not so responsive as if it’s delayed
Is the smoke on the outside? Probably just oil or cleaner burning off. Is the throttle body and throttle cable hooked up properly? The the entire exhaust hooked up? Is the fuel pump strong? Delay could be a lot of things
I got a 07 crown Victoria 4.6 engine but the Valve covers are different is there going to be any Issue or do I have to change them
I ran one on the passenger side on a GT. It seemed fine
Does it matter if the engine has an oil cooler or not?
No. Just remove it and put the mustang oil filter adapter housing on. Just make sure the mustang one is clean from anything the old engine may have run through it like metal if there was a rod knock. I believe some police cars and P71 Vic’s had the coolers
@@justin.c_svt thanks and thank you so much for responding, had to subscribe…great channel
Thanks 👍🏻
Lord have mercy all that water!
What do I do about the fly wheel ? I have a 8 bolt Manuel fly wheel. And the auto 6 bolt fly wheel. Do I buy a 6 bolt Manuel fly wheel for a
Yeah, that’s the only thing you can do. You’ll have to buy a six bolt fly wheel. Yours was a Windsor engine before and now that’s a Romeo.
@@justin.c_svt can I still use the same clutch
That’s a good question. Sometimes you can. If you look up the clutch on the website where they sell it, it might say specific years that it can be used and sometimes it references 96 to 04 which would include all manual transmissions (T45 & TR3650 of the GT)
@@justin.c_svt when replacing the rear main seal, do I need to replace the oil slinger that goes on after the rear main seal is replaced
@@justin.c_svt mine is bent just a little it looks reusable still
Why change the oil pan out at all, shape looks the same
Because the oil pickup tube will smash the bottom of the pan and starve the engine of oil. The oil pan on the Mustang is a different depth than the Vic and the oil pickup is as well. You need to use the parts ford changed specifically for the mustang. The pan on the Vic won’t fit in the Mustang K member.
@@justin.c_svt oil pan on Vic won't fit mustang k member is the answer I was needing I guess, this has been verified?
@mfjones2217 Do you think ford would have changed it if they didn’t have to?
@@justin.c_svt I'm just asking has anyone tried to actually fit it in there and what are differences in oil pans recon, we weld up coyote pans for CV cross members all the time, bump on pan hits cross member u just square it off, only difference I see is it may drag the ground if pan is deeper on crown Vic pan,
@mfjones2217 This video is to show the right way to do the swap and everything you need to swap over so most people who do this won’t complain that that the parts are different. It’s not about how to modify and make things work. I’m not going to tell people how to modify and maybe make it work. Change the mustang specific parts over and have piece of mimd that it’s the way it should be and no short cuts were made.
Hello I have a 2011 V6 mustang with a bad engine. Is there away I could put a crown Vic engine in my V6 ?
It would be very difficult to make it all work with the computer. You would have to swap everything over and still risk a lot not working. I’d just replace the V6 with another V6
@@justin.c_svt ok thanks alot
Hi Justin ' I just have a question for you? I'm trying to built a 2001 mustang gt ' it's gonna need a new engine ' a 2006 crown vic will work for my car??
Yes it should. Depending on the year the timing cover might need to be swapped. Compare it to yours
@@justin.c_svt thanks man ' ' I'll do that when I get the crown vic engine!
Could I put a 2008 crown Vic into a 2007 v6?
No
Did you prime the oil pump before first start?
No it should have oil in it already since it was a running engine
What about the intake manifold, use the mustangs or the crown Vic
You can use the Vic one. Just have to take the top part off and put the mustang one on.
@@justin.c_svt will there be any power lose from using the vic intake and swapping the top part of the mustang on it?
No. It’s the same intake manifold. Just the plenum and air induction (cold air intake) is different. As long as it’s the PI intake manifold and not an older NPI one
@@justin.c_svt thanks
Hey Justin, I just purchased a set of intake manifold gaskets ( felpro) they are 1 piece for my 4.6 GT motor, I noticed the intake manifold that I have have individual silicone seals. Are these types of gaskets interchangeable? The seals that I have on my current intake looks like the dorman 615-175GA. I know it's an aftermarket intake manifold
If your intake manifold has the gaskets built in you don’t use the felpro ones or any other ones
@@justin.c_svt Thank you. They look to be in good shape. I imagine they are reusable
@@brucewayne2773 Yeah they can be
@@brucewayne2773 sounds like somebody put a crappy aftermarket Dorman intake on your car
@@neilbrown82 Actually, the Dorman intake is a good one. It's a lot better than the OE one that came with it.
Hi I have to do a swap on my GT and I found another one that was in a wreck the guy said that the engine valve cover was cracked and the harness got messed up I can just swap it do you think the process will be hard? Thank You
As long as pieces of the valve cover didn’t fall in and contaminate the engine
@@justin.c_svt UHM I don't think so I'll ask you have any tips on how to do the swap?
My brother has videos on his RUclips channel of us removing the engine from an 03 cobra. I’d start by watching those
