Corey Burns Standard cobra 03/04 heads flow more than 241s and here in aus were we only have 5.4s that's not the case. Any you can make a lawnmower haul ass with forced. Its another debate. Nre make their 5.4 dev 1500hp. Besides we don't even need a ford v8 here to beat an ls , our 4l six turbos detroy ls every day. Google 4l barra 2000hp running 4.7et. Saying that i agree the ls are a great engine.

Very good vid. I enjoyed seeing one of these engines torn down. And the production and editing and camera work were superb. Congrats on a very professional video.
good video my brother ,,i got 2004 maruader 112,000 miles on it..eventually im gonna have do my engine it has that rattle sound only when u frist start it up for about few seconds then it goes away..maybe timming chain tensioner latting the chain slap to the oil fill them or hydraullio cylinder in the tensionerare alittle worn
She got Hot, many of these motors are hurt from running lean or low oil pressure. I have two cores in my garage awaiting rebuild this summer. I look forward to your video and future build!
Evan Paul Smith Falcon Fogolin that and the fact that the driver side head is a “dead head” coolant can’t leave the rear of the head and causing temps to get high and valves start destroying the seats. Need to put the mod on to let coolant out the freeze plug and to the other head
@@mikebing1230 I believe Livernois solution to be the best, I would look into their method before making your choice. despite having a set of DC heads I am going to use their method. basically routes the oil down to the pan as not to create any Windage from other methods. I am considering a mechanical oil pump, and dual pump return style fuel system.
amazon sells a lock out kit for 2v/4v. it significantly helps timing the 4v motor. no need for setting up marks on the crank unless you have aftermarket cams.
Thanks! I looked up that tool and I am going to buy that and along with a few other tools to work on mod motors. I miss the old pushrod 5.0 engines. Timing the 5.0 was cake! I guess once I do it a few times, timing a 4v engine will be cake too!
rashad smith nah we haven't done much if anything to the cobra in awhile. it's just been sitting. we sadly lost the footage if use putting the engine in.
My 04 has a blown motor from overheating. Im not sure what happened really because I wasn't driving. Does anyone know a good place in California that rebuilds these? Local shops scare me.
I'm guessing so the cam wouldn't spin when he took the timing chain off. If the cam snaps around from the valve spring tension, you can knock a piston with a valve.
+Pasta Sarmonella E-Specialé haha I know. I was joking about how the LS design is essentially ford's 351w. but yes if you want more cubic inches ford's GT500 5.8l 351ci is the biggest DOHC 4v currently. virtually impossible to put onto ls block though.
impossible. although the LS uses ford style 10 bolt heads the LS heads a longer. the LS uses so many 302, 351, 427CJ, design aspects that no wonder they made it to preform against the mod motor when their old tech 350 wasn't performing.
Skrix Fox nope wasn't NOS, ran super hot due to the intercooler pump going out during a WOT pull for awhile, didn't hear the pre Det that was going on, so ran super hot, on top of being lean will destroy a engine just as much as NOS would.
Jesse Cox It looks similar I think the coyote is aluminum and I noticed it doesn't have the same variable valve timing, I just saw the photos at the end of the video, looks like he has some hairline cracks in the cylinder heads.
So it looks like DOHC really aren’t that complex? I don’t see the big deal here. I’m constantly battling between GM and ford and this is why. Their v8s. Can someone bust a myth for me and explain why?
The DOHC can usually spin faster and the 4 Valves make the heads flow very well, thats why these engines make hp per cubic inch than GM Pushrod counterparts. The honest truth is the Modular engine is more modern technology and innovative than the older tech/design of the LS/GM engines.
Jesse Cox what about it being “so hard to work on”? Compared to pushrod engines. I mean why does NASCAR, NHRA, Monster Trucks still use them? Can’t wrap my head around it lol.
@@joshuachilders129 to put it simply its easier to remove their cylinder heads without doing the timing all you do is remove the head bolts , and pushrods and etc
Also can you give the setup details on what this motor was setup w/ prior to the inter-cooler evaporating? And which type of pistons/rods/etc are you going w/ for you new build?
Teej Daniel Helme 98, 00, 01, 03, & 04 cobras were all 4.6L DOHC engines. In fact there is no 5.0 Cobra. The GT500 has 5.4 or 5.8 depending on the year. GT350 is 5.2. Google it.
This is over 10 months old and when will you have the motor in Lord when will you have the motor in and built I will race your slow cobra when u get it in 😎
Finally, a car video with NO TALKING. Just pure work. Thank you.
Guys rant about LS, these are such a kick ass engine
Yeah it takes a supercharged 32 valve v8 to beat a na ls1 well except the corvette lol

Music was a nice touch. What caused all the damage ?
Someone bless these two lads with a cordless 3/8 impact...

i had the same damage. too much boost on mine. Awesome video btw!
You mean not enough octane
Could have done without the music, and just a slight narrative as to what you were doing and what you found. Good video otherwise!
anyone else notice the second song is in thatdudeinblue's terminator review intro? no, just me? aight
Great video. Keep them coming. I would love to build a spare motor for my terminator
Thank you. I will. KB install video is probably what's going up next.
as you can clearly see in the video. I did 98% of the work ;D
its an engine not a motor!!
Is this the same set up as the mach 1s minus the supercharger
@@shawnwashington8302 pretty much

when is the build up video coming?
Nice video, I'd love to see a reassembly one.
Ray Massung In the near future I'll be putting together my Teksid 5.0 stroker and I'll video that 👍
Can you give me some tips on breaking in my engine im getting new pistons and rods and would like my piston rings and bearings to last me a long time
Those cylinder heads are massive compared to a 5.7 hemi of that year
What is ALL that noise in the background? Annoying. Thank goodness for the MUTE BUTTON!!
Hello! Can you make a video on how to time a 4v engine?
rashad smith yeah I should be able to pretty quick. putting a 4v together soon.
amazon sells a lock out kit for 2v/4v. it significantly helps timing the 4v motor. no need for setting up marks on the crank unless you have aftermarket cams.

What's up Jesse! Did you get that motor put back together?
rashad smith nah we haven't done much if anything to the cobra in awhile. it's just been sitting. we sadly lost the footage if use putting the engine in.
My 04 has a blown motor from overheating. Im not sure what happened really because I wasn't driving. Does anyone know a good place in California that rebuilds these? Local shops scare me.
Did you ever uploaded the other part of the video where you actually rebuild it?
Quick question. At about 2:44 and 2:55 why does the guy hold the cam?
I'm guessing so the cam wouldn't spin when he took the timing chain off. If the cam snaps around from the valve spring tension, you can knock a piston with a valve.
How many miles?
how long did it take to tear it down?I have an 03 Cobra to.
Paul Montecinos Maybe 45 minutes to an hour.
NITROUS LEAN OUT?
Hey great post. Those pistons are bad and what cosed that. To much boost ?
Looks like they melted. My guess is nitrous or some 5th gear pulls
Wonder what happens if you put these cylinder heads onto the LS engines?
You mean the Chevy 351w?
Jesse Cox No I mean those modern type Chevrolet LS series engines that are a common engine among engine swapping in pretty much anything.
+Pasta Sarmonella E-Specialé haha I know. I was joking about how the LS design is essentially ford's 351w. but yes if you want more cubic inches ford's GT500 5.8l 351ci is the biggest DOHC 4v currently. virtually impossible to put onto ls block though.

I have an 03 cobra. I need to tear mines down to and replace pistons. Where do i find and factory manual for rebuild??? Or I'll pay u to do it...lol
How many miles did this engine have on it?
It had 102k
+572jpr 102k Miles. melted pistons somehow
+572jpr more like lean.
Skrix Fox nope wasn't NOS, ran super hot due to the intercooler pump going out during a WOT pull for awhile, didn't hear the pre Det that was going on, so ran super hot, on top of being lean will destroy a engine just as much as NOS would.
The Pistons look like a victim of nitrous. She got very hot!
Hey, where’s the trollstang engine?
Ps love this video
How similar is that to the coyote engine ?
09victoryrc fairly similar. but the Coyote has very few compatible parts.
Jesse Cox It looks similar I think the coyote is aluminum and I noticed it doesn't have the same variable valve timing, I just saw the photos at the end of the video, looks like he has some hairline cracks in the cylinder heads.

Was the car untuned? or run on 85 octane........
intercooler system ran dry. no idea how.
+Jesse Cox Sorry to hear. I try to check mine as much as possible. It probably got really low and then evaporated the rest out
+Justin Johnson yes I think you're right. I keep a very close eye on it now.
Also can you give the setup details on what this motor was setup w/ prior to the inter-cooler evaporating?
And which type of pistons/rods/etc are you going w/ for you new build?
Mike Lewis stock engine, stock Eaton, pulley and tune.
Should have used more of a star pattern while removing the heads
Tim Bowman yes, but theses heads are trashed anyways.
what's a rebuild like this cost ?
lot of variables but id say ball park 3000
@@JesseCoxVideo fuckkkkk
I swear this song is like the Terminator theme song. is not the frist time I heard this song in a video involving this engine.
Nice... had to mute music ... otherwise great tear down video 👍
agreed.
100bl music ruins the video in my opinion
Music is dope ...hella perfect!!..subscribe asap!!!
2003 cobra 4.6L? Are y’all joking? The cobra motors (supercharged or not) are 5.0s and up

Can i swap out a 2v head and swap in a 4v head in a Crown Vic?
I have been trying to find this out too. Is the crown Vic a SOHC though?
