100k subscribers finally

Strange how these vids are some kind of mesmerizing therapy for me, even though I've never totally built an engine other than add-on stuff. Thanks LT for another quality video.

I think the inside of that engine looked pretty good for 180,000 MI and probably would have ran fine under normal conditions, but I know how you are and I think you want it almost like new which is not a bad idea

Don't forget to upgrade the secondary timing chains if you put cams and springs in.

I dig the 3c's idea. Always love seeing n/a builds on the mod motors since everyone just throws boost at them!

Congrats on 100k subscribers!!🎉 Someone never kept up with the oil change intervals, I’d see how much it would cost to get machined. If it’s too much then go with back up plan 8.1 lol.

Looks like the previous owner didn't keep up on regular oil changes and probably run the hell out of it. On another topic, you do know you can get a drain pan that fits on the legs of your engine stand. It's better than having to keep a mop handy.

The Navi and 03-04 Cobra secondary timing gears are different from the later Shelby. You can use the Navi, Cobra Valve covers on Shelby but the Shelby Covers wont clear the larger Navi and Cobra gears and chain. Make sure you get the iron primary chain tensioners and not the plastic one. Also you can ditch the stock pan and Shelby windage trey for the Coyote pan and windage trey/gasket combo with only a small mod for the oil pan pickup tube. A stock oil pump with TSS billet gears and a metal back cover seems to be the best combo. Avoid the adjustable primary cam gears. Use the multiple keyway crank and cam sprockets or shim the stock cam gears. When putting the cam towers back on, you have to go down alittle on each at a time or they will snap right where the bridge starts. The 00' Cobra R Cams have alot of lift for a mod motor but duration was pretty low at 212@.050. You can go into the high 220s- low 230s and have really good drivability.

👍 on the 3Cs! I’d vote for the CNC work on the heads and set the compression as high as possible. When you turbocharge it, just plan on E85. With all that valve area, it won’t need a lot of cam, maybe upper 220s on the intake. This build looks very interesting! Thanks LT!

Bummer about the blown motor. But I know you'll do it right and we get to be along for the ride. Can't wait to see it ripping. I think the 400whp goal is totally attainable NA with how you plan to build it. And it will be a strong base for boost in the future!

I'll never build a 5.4 but have been curious what this swap would turn. Ausie parts make it all the more interesting.

So that’s why the Navigator was in the junkyard lol!

"I specialize in things that don't make sense." It has been a very long week, and this gave me a smile. Thank you.

I think a modular V10 build would have been pretty nutty, though I understand it's not exactly a performance motor in stock trim.

Love the love for mod motors and even better that your doing high compression!

Like your content. Hate your giant tag lines to get attention. No “massive fail”. I worked for Ford Powertrain from 1998 through 2007. I watched the mod motor family grow from paper design to many iterations produced in Romeo and Windsor engine plants. As quality manager in Romeo, my organization tore down thousands of development, durability, and customer return engines. Aluminum bearings are unforgiving. Lead Babbitt will absorb foreign material and to some extent, self polish. Aluminum which meets debris results in a score mark proportional to the size of the contaminant. Then gets expelled and trapped in the filter. For 200k miles, those bearing looks great. The engine does need a rebuild, especially if your going to lean on it. If you measured the bearing clearance, I bet it wasn’t as bad as you make out. Hate the drama. Like the facts.

Hey LT you hit a 100k congratulations. Great content and work man.

100k! Climing the hill to one mill! You definitely deserve it. With that big block your gonna need your NHRA certification. Also porting goes a long way on the tumble port heads.

One of these days go full odd ball and do a twin turbo Triton V10 👌

Congrats on you goal of 100k subs before the end of the year..let's hit 200k in 2023..keep it up

Way to go LT. You built it to 💯. Been enjoying the content since you started. Keep building and inspiring. 🎉

Congrats on 100,000🎉 been here since

make sure you use a mellings high volume oil pump. the factory oil pump backing plates tend to flex and bleed off oil pressure at higher revs.

This should be a interesting build to see come together even though I am a chevy guy Ford does make some good stuff. How about cleaning up the intake and exhaust ports for some extra power? Just a thought. Great video LT and looking forward to seeing this one all built! :)

I love the idea of not following the crowd ... I have always done this from I bought my first car at 16 no motor no trans no interior after school work and weekends paid for everything myself . At 70 yrs I still do it.

Congrats to 100k Keep up the 5.4 mustang build, really enjoy it

Nice build love it!! Thanks

Love all the stuff you do dude!!! So awesome to throw in a little LS chip shot lol Stay safe!!!!

They have stroker kits, as I was in the 4.6 crowd with my built 97 Thunderbird LX. So much fun

Excited about this build. I'd send those heads to Livernois for a quick CNC Job. Only charge $700 for it. Not a bad price. That with the extra cubes and 10:1 I think 400whp is reasonable. Think about a 5.3 LS, it has worse heads, less displacement, and yet people make 400whp with a heads/cam/intake package all the time with those.

Well damn. Things just got way more exciting. Can't wait for this thing to be all set up, it's gonna be an awesome build.

Glad I just found this channel awesome content!!!!

I’m glad you tore it down. My rule of thumb is tear it down unless you’ve heard it run and know it’s healthy. LS and Coyote swaps are great but I’m with you on this project. Congratulations on 100K!

Congrats on the 100k subscribers. You asked by the end of the year and by Goldie you have them lol. Great video. Thanks for sharing.

I like the idea of the power goal with the 5.4 for the price of a 5.0. Excellent direction to take this!

Watching your content since the AWD obs Chevy build. This build here is exciting and totally different. Stoked to watch it come together!

Definitely a sign of dirty oil/ or not having the oil changed more frequently

LT congratulations on the 100k subscribers as I have said not a big Ford fan but I think this is going to be fun. I think the tear down revealed a lack of regular maintenance

I used to have an 01 cobra and always wanted to do this to it. i'm excited to see some people still want to do this swap.

That Navigator motor is definitely more unique than a5.0 or 7.3. Looking forward to seeing you build what you want :-)

Congratulations on 100k!

Congrats on 100k subscribers! Well deserved…this channel is under rated

I love your content and I’ve built all of my motors in the past for my cars me and my dad built my first big block for my truck in highschool it is a 454 block bored to a 472 with Arias pistons h beam rods and a scat crank and it made 410 horse with a towing cam it made 600 pound feet of torque I was amazed at what I could do but you gave me the courage to try to do it all myself

Glad it's you and not me with a Ford project. Hahahaha. Love your channel. Keep it going!

I’m putting the entire powertrain and wiring from an ‘01 Navigator into my restored ‘77 F150 Shortbed 4x4. I also have another donor car that I just pulling the engine and trans so I can have an extra transmission in case issues appear later on and so that I can have a spare block set aside that I can build for boost over time so I can have a supercharger kit on it in the future because a Coyote supercharger kit on top of the 5.4L with the MMR intake adapters would fit and be just fine for my truck. I got these two parts cars for so cheap I couldn’t pass it up. I was gonna go the coyote route but I’ll settle for a poor man’s coyote if you want to call it that. Lol. Looking forward to this build.

I like your thinking about the 3 Cs. I'd find it hard to belive you couldn't equal or surpass the coyote with good cams, 10.5 to 1 plus that intake. Might not be as tame as the coyote on the streets due to the coyote having variable cam timing. But it should sound better and be more fun to drive lol

I had seen the awd Silverado for sale already, wish I could buy it.....but too deep in my own projects at the moment lol. "Teaching" myself (by watching you and others) how to do all this work. Just picked up my first ever engine to tear down and rebuild, swap into my truck as a test build. Unknown mileage gen 3 5.3 that I'm converting to run with my gen 4 wiring harness and ECU in as much a plug and play build as possible, beat it to ensure I built it well enough to survive, then turbo & learn to tune ECU, upgrade the tranny to handle the added power. Simple goals, and mainly for building confidence before pursuing something along the lines of awd conversion turbo street/strip truck.

Congrats LT on the 100k... Keep up the videos!!

Wow congrats on 100 thousand and the 25k for the copo is so tempting lol sucks I'm in Cali and the smog would kill me currently trying to find a 2007 and newer escalade or Yukon Denali to build a 75 or older version of this truck have a 2005 silverado currently I love with the l33 in it

I love the quality and depth your projects go even having a small garage. It gives all of us other DIYers hope to build as good projects as you do.

Congratulations on 100k subscribers LT!!!

LT dude i would love to sit down and talk about various engines that are either neglected or just not loved enough, but im in NY, so i'll have to wait till one of us are in the others neck of the woods,

Always wanted to do a 5.4, seeing what you have alrady went through so glad i never pulled the trigger.

Just subbed, and oh hey, 100k!

100K Congrats!!

I like your choice using a 5.4 always wanted to do this swap they are a dime a dozen and love boost and are pretty stout from the factory.

Me thinking: new bearings polish crank with Emery cloth and send it LT: that doesn’t make sense 😂 Love the channel bro

You can find forged parts for the rotating assembly for about 2k but the cams and supporting parts is what will get pretty pricey. But with a budget of about 6k I’m sure it’s possible

Come on LT that was a real rookie move turning the motor over with no tray underneath LOL

Hey congratulations on 100k! I’ve done a ton of engines… this engine from what I’ve seen it wouldn’t have been good for what you were going to do it stock, beating it down till you really build it, but with that being said you could take this engine put it into a navigator new oil and filter obviously and it would’ve run good and quiet for quite awhile. It’s almost 200k with a few missed oil changes I reckon. Not a bad as your thumbnail suggested. Again, this engine wasn’t going to be a light daily driver. You were going to thrash it from jump right from the junk yard.

And that's why you keep up with maintenance on any motor. The rods are the week spot can usually only handle 450rwtq ish. The cranks if cast can handle 600-700rwhp and forged cranks north of 1000rwhp. Oil pump gears should be upgraded as well with arp every were

Congrats on the 100k. Crazy to think I’ve been here since the beginning of ugly truck!

Looks like possible oil starvation? Put the Melling M360 on there. I'm pretty sure the 4V comes with the larger pickup tube already (15/16").

Ur right - if that was an LS, you wouldn't be having problems. From my experience, the mod motors I owned never lived past 200k miles. Hated working on them too, especially with all the little Ford details that are just....maddening.

Sucks that happened to you, but you answered every question you had. You will have a killer motor when it's done. Not to mention unique build.

Congrats on the 100k subscribers!!!!

Life is like an engine. Never know whatcha gonna get. Lol. Love all the engine builds

There are two kinds of mustang guys..... "It's Procharged, and makes like 900 horsepower" but it's stock besides a muffler delete, and a power steering pump going out Or "Yeah it's totally a stock motor, ignore that whine, my power steering pump is going out" lifts hood to a 2.1 liter blower, running e85 and drag radials on stock wheels.

Get that shirt made and sell it on your merch store: "I SPECIALIZE IN THINGS THAT DON'T MAKE SENSE!" It'll be great!!!🤙

I thought you were going to say the block is cracked. Bearing wear on a high mileage wrecking yard motor is not a big deal unless the crank is really scored. Forget the boost and do the 3Cs.

100k! Congrats

Yes! 100k Subs, that is awesome!

I wouldn't say massive fail. Pretty much what you'd expect for a high mileage 4v out of an SUV. Do rods, pistons, appropriate machine work, ring gap. Refresh the heads & have fun.

I'm excited for the Navi build! Always wanted to do an intech 4v

BROO 100K SUBSCRIBERS it's about time you deserve it Lt your an amazing mechanic it's time for you to blow up on KZfaq let's freaking gooooo🤘🤘🤘🤘

Congratulations on 100k subs. !!

Looking forward to this build I'm wanting to do this to my 10th f150.

i love that your building something different but yes agreed an LS youd be done already

Got that right LT. My 99 silverado 5.3 has 319k miles all original internals. I would say been serviced properly but my boss had it from 2007 to 2020 and he just topped it off when the low oil light came on. I've done oil changes every 3k since with shaefers moly additive and some synthetic blend 5w30.

I also clean the floor with break cleaner. The 5.4 4v has all the basics you need for 400 whp NA. Your basic engine is in decent shape. Those bearings did their job. I would clean the block, check the bores and main bores. If it needs to be bored, fine. If not, ok. If the main bores are good, I wouldn't line hone it. I would measure the crank, and grind if needed. If not, I would carefully check all the bearing clearances. I would use good I beam rods (H beams are heavier and weaker than a proper I beam. The debate on this is absurd). Select an appropriate piston (I like DSS and Mahle). I would hone the bores with a torque plate, and deck the block square and equal. If possible, zero deck the block. Use a steel top and Napier second ring set. I would do whatever the heads need, checking the guides carefully. If the valves are in good shape I might re-use them. Cut the seats, surface, assemble with new seals and lash adjusters. Realistically, it will need better springs for both boost and aftermarket cams. Obviously you will need new chain guides, tensioner, and chains. I would go adjustable because I degree everything. Cobra oil pump and the right pickup gets you there. I didn't mention cams, because that's a conversation all it's own. I suppose we can do that. If you want to modify the heads, I would poly quad it before I ported it. I say all this as a professional engine builder with some modular experience. Really, your engine isn't all that bad, the situation could have been worse. I had suggested a 6.2 Boss before. Good luck with whatever you decide.

All the comments placed on top of what you say were hilarious to see. I know it is serious but at same time it made me chuckle out loud.

This guy looks like the "it's my good hand" guy from Scary Movie.

I have a 99’ Navigator with this motor and same mileage, 178k. I will be watching this closely as there is not much aftermarket support for these. MMR makes an adapter plate set to use the 5.0 coyote intake on the 5.4 32v. You can bolt a coyote supercharger manifold on it!

Congratulations on reaching 100k subs!! I'm at 166 lol!! Dude I hear ya on the Fords, I try to give them or any manufacturer the benefit of the doubt, but I always come back to GM engines.

14:44 i knew it. i did say on your last video you should go with option 2. im a mechanic myself with my family being a bunch of people who fix stuff. from now on tear everything down so your safe. cause this would have gotten way worse or even the engine snapping a rod(from what i know about this particular 5.4L, its an economy motor, not a powerhouse. the main problem is usually the oiling system from what i recall) plus the rods in these engines are actually weak.

"Not groovy". Topolinski would be proud!

Brother I can't wait to see how this goes. I have 3 or 4 Navigators in my you pull it and I have a 03 Crown Vic P71 I was thinking about 5.4L double cam swap and I also was thinking 6.0L Ls swapping. I would love to make 400 to 450 wheel horse power with a twin cam 5.4L instead of a Ls swaping. If I can do it for a bit less then a Ls swap. O r even just a bit more. Thank you brother. I WILL BE WAITING FIR UPDATES.

Congratulations on 100k subs! (Also love that Cleetus hoodie, I have the same one!)

Im rebuilding a 6g73, its been a lot of fun, im anxious to see the outcome of your and mine!

its a massive bummer that the engine was in bad condition, but I am REALLY excited to see where you take it.

Omg no way you haven't sold the coppo truck yet? That is like my dream truck! I went to the link and saw what you were asking and I thought that was crazy cheap for what you have done to the truck. I wish I had that kind of money comma I would gladly give you your asking price!

Good video, I like

Congrats on 100k!!!

Congratulations on 100k buddy and nah I really love the copo truck way cooler than the stang best motor Ford ever made was the 300ci i6 absolutely unfriggin killable

Lincoln Navigator engine outside, Trinity 5.8L GT500 engine inside...ported heads & intake, custom grind cams, billet oil pump, 4-bolt mains, it's gonna be a beast!

I will never say the 5.4L is the best ford motor. But I will say that motor can be found in many E series service van with 200k+ on them.

I’d spring for a 4.415 stroker crank, clean the bore up .020, and have a solid base that’ll take the abuse you’ll inevitably put it through. In for a penny, in for a pound, I say…

Congrats on the 100k subs 🎉🎉🎉

David Farlow has a badass big Turbo Mod 5.4 he drag races!!! Low 4s in the 8th!!

Congratulations on 100k
