It’s 1:02 am and I don’t even have a mustang....but I do want to install a cam on my non existent Mustang after watching this

[@jhershy1381]

You should do that. Dreams are real

[@blackpanther04ltc91]

I had that dream for a while then it finally came true you should keep dreaming don't give up

[@checo_1777]

It’s been 3 years, did you ever get a mustang?

[@Tiktokis_plymouth_satellite]

We legit doing the same exact thing rn

[@DoyleShadduck]

Git er’ done!

[@CameronHall-wq9tk]

Aaaaawwww yuss. I haven't been this excited for an upgrade video since the ITBs for the S2000!

Cameron. Hall c ITB's on the mullet mustang would be sick.

The content on this channel is top notch. Hope these guys make it big.

[@speedacademy]

Thanks so much, means a lot to us!

Fist bump fail lmao

[@MasterChief-sl9ro]

All you have to do is remove the intake rocker that has pressure on it. The cam will not move when removing the phaser...

Replace lash adjusters and rockers as well at this point 👌

[@taikyumedia4929]

you guys deserve soooo much more subscribers and views !!! You have by far my favourite channel since I found it. The best stuff combined with the best humour ;) I love it.

[@speedacademy]

Thank you!!!

[@feellnfroggy]

If you set the crank at about 12-14 deg from top dead center, you hit a spot in the cam where no valves are under spring pressure (or are all under equal pressure, and when you release the cam pulleys, they wont spin on you, and you don't lose alignment with the crank. Little tips from hard lessons learned.

[@rondaroushy651]

God Bless you, I'm going to be doing an entire top end rebuild with new timing components and I was wondering if there was a spot where no springs are under pressure.

[@BJ-fk9sq]

So is it 12-14 degrees before you hit tdc? Or 12-14 degrees after you hit tdc?

[@feellnfroggy]

@@BJ-fk9sq when you rotate the crank with valve covers removed, you will see when you hit that sweet spot. No pressure on any of the valves.

[@BJ-fk9sq]

@@feellnfroggy ok, thank you!

[@marxieuwu3573]

I would absolutely love to see you guys work on a 2000 Lincoln Town Car, make a super cool sleeper build, since it's a Ford Modular V8 it shares many performance parts with the older Mustang V8. Cams,headers,turbo or blower and big meaty tires

[@Tomatokillz]

man i had to come back and watch this again, I miss this intro! should bring it back for the nostalgia one time

[@BoostedMarcelo]

Good job guys!! Changed my springs, cams and timing chains on my 2007 GT and it was a badass experience

[@speedacademy]

We certainly dont want to do this again... ever haha

[@damianfro4855]

The mustang I bought was a half finished project, I put 5.4 cams from a 3 valve truck, and I havent had problems so far. If u want a more mean sound, do it. I didnt have a choice, cause I was on a budget, and I could not find any 4.6 3 valves in the junkyard

[@1DoPeS14]

Only speed academy can get me excited for mustang upgrades keep it coming

[@Large_Sarge]

Ive seen curved jaw vice grips used also. It's cringe but has to be done sometimes. Just got some ford performance cams and long tube headers for my 09 S197. Can't wait to do this job. Thanks for this video.

[@garymcmullin2292]

the more I watch work done on the top of those modular motors the more I like the old pushrod motors. For grip on the cam body when lining up the phaser sprocket try a small piece of leather or Naugahyde in the jaws of the pliers.

[@boostedbuiltgarage]

Another great detailed video guys. I'm sure this will help many people!

[@williamhayden4372]

HOW ARE YOU NOT GUNNA INCLUDE AN EXHAUST CLIP

[@speedacademy]

Sorry, NV was closing so we had to hurry and we thought the dyno video would be ideal to show the exhaust note off

[@williamhayden4372]

No worries fellas, keep pumping out the good content on that stang.

[@abrideforchrist4247]

I use pearl necklace drop it down the spark plug hole till I got almost a whole necklace in there.. . and then I slowly roll the piston upward till it pushes on my pearls and my pearls hold my valves in while I make spring seal changes... and it works on all engines..use it on lawn mowers to.....

[@georgewilliams9014]

You guys are great! I feel that I can do my own cam install. Thanks for the encouragement!

[@JDIZZY024]

I have a 05 f150 with the same engine I'm looking to do a cam swap, with this greatly detailed video I feel that I could do it myself 👍🏻

[@ptp954]

Absolutely love this channel you guys deserve way more subscribers

[@speedacademy]

Thanks!

[@RivalBro]

Enjoying the Mullet Mustang series. Would love to see the same kind of videos, you buy a car and work on it to make it better for track, not just drag. Would love to see you compare the same era cars like 2005 G35 which was a competitor to this.

[@250hdd]

You guys deserve more subs . This is honestly one of the best car channel on youtube right now

[@speedacademy]

THANK YOU!!

[@PoorManMods]

I did the valve seals on my 1JZ, one of the keeps popped off and fell into the head, i eventually somehow got it but about shit my panties

[@therealboofighter]

Poor Man Mods Dude, your video of you installing your cams helped get the confidence to swap mine out on my MR2. So thank you.

[@PoorManMods]

hell yeah! thanks for watching :)

[@speedacademy]

That was the nightmare, you can see we jammed all the holes full of rags to avoid that happening.

[@griptact4666]

i don't have any cars that these guys have but i still watch all the videos as if im about to do the same upgrade lol

[@doctorlobsteroctopus]

lmao me too. it's just entertaining and you learn a lot of technique and proper ways to do these jobs.

[@tonygonzz]

When will you guys have an update on this build! Exactly the mods I want to do with my 3v. Looking forward to more great content.

[@lb9gta307]

It'll be interesting to see what numbers Sasha pulls out of it now.

[@BjRay_TV]

THE ONLY SURGERY IM INTERESTED IN 😊😂

[@mlhebel]

Not bringing the engine to TDC will not reveal how worn the chain and sprockets are. When I replaced the all the timing hardware I found I had to move the driver side cam about 5* to bring it back to TDC when all the new parts were installed . This out of time cam shows up when comparing O2 sensor readings. Everything else was a 100% on my 4.6 and ran fine but the O2 sensor reading were out of whack (comparing cyl banks). Couldn't find an explanation swapping sensors of course confirmed it was not sensors. It was after changing all the timing hardware due to a bad tensioner and I happened to look at the O2 sensor data afterward that I discovered that the readings were now normal.

[@mlhebel]

Use an ARP bolt on the sprocket (phaser) one time use bolt won't have to be replaced if it ever has to be disassembles again. I also remove the fuel pump relay and crank the engine till I see oil PSI when ever I have opened up the oil system. That was a scary sound but the prelube probably saved it from damage.

[@Beakz_]

God that first start up scared the living shit out of me! I don't even like mustangs but damn did that sound BAD! Good thing it was only the lifters though.

[@trtlepwr]

Beakz_ yeah I thought the chain gone fucking nuts lol

[@aaronhebert100]

Mine is doing this after a stage 3 comp cams install. How did you guys fix the issue? I spun the motor over a few separate times until the oil pressure was up and still has that god aweful noise. Please help lol

[@truthteller9562]

What a let down no bumpty bump

[@guynoir3116]

The one downfall of a cams swap on a 3 valve is that the stock bottom end will probably fail , catastrophically , if used frequently at R.P.M.s approaching 6400 .

[@flubdreload2818]

Richard Skipper most likely the stock rods can’t handle 6,400RPM+. Connecting rods are under a lot of tensile and compressive loads constantly and if you’re approaching 6,500+ RPM consistently, you’ll probably end up snapping a rod. the crank is pretty stout so i doubt its the crank that’ll go first.

I know the car Pete's Evo is pretty much complete but i hope some stuff is possible for some content lapping or just random updates. There is only so many times I can watch the videos of it!

[@speedacademydave]

We're definitely going to do a track test of it this summer, since we're swapping out the coilovers for some Fortune Auto 500-series. Pete wanted something more comfortable for the street that's still track-capable, so we'll see how he likes the 500's.

Awesome really looking forward to it!

[@ZakPhol]

Great video! At 18:21, I can so relate. :-)

[@Wooley689]

Nice video. However, aren't you supposed to run the engine at a constant 3000 rpm for thirty minutes for break in?

[@yanscvwoods6648]

Definitely just made my life easier.

WHY DO I KEEP LISTENING THAT SONG WHILE IM LOOKING AT THIS......time to do some sketchi sh..t doo daa doo daa, GOD LOOOOORD HELP ME WITH THIS 2.........................

[@Gear1993Head]

Is the compressed air into the engine to keep the valve from dropping into the cylinder?

[@BrookieCooki84]

Gear1993Head xxx correct

[@Adam_824]

Always enjoy your guys content

[@luzruotolo5487]

Hi, I'd like to ask, in the video, that I saw that, you've replaced all the Rocker armrs and lift Adjuster and changing the cams! At the same time. How was it possible ? Please explain me. In advance Thanks you so much . Francesco

[@lordXguru]

stage 3 or 4 gives you that big lope you were mentioning

[@ryanv7195]

What did you do to prime the engine?

[@aintnoDat]

That sound on first start was scary!!

[@johnnychambers1015]

hello i was wanting to know where did you get your blue hound valve spring compression tool im need one.

[@RobertKohut]

Great job, a little "back yard" but you got it done. A better sound clip , warmed up, and from the rear would have been nice. Sounded a bit "lopey", but hard to tell with the brief moment you had it running.

[@speedacademy]

We're saving it for the dyno video, lots of good noises coming!

[@PolyFPV]

How does Doug DeMuro have more subs than this channel?!

[@tagrav]

Dougs channel fits a broader spectrum of car lovers. if you don't care about wrenchin then this channel would kinda suck for you.

[@TassieLorenzo]

Also Pete, Dave and Ken always build cars perfectly and expertly, which can be a bit... predictable I suppose. It would be fun to see them build a car badly on purpose (I suggest RAV4 2-door convertible!).

[@lolman77]

18:20 That big fail though

[@harrylinka5227]

Are you not supposed to lockout the phasers on those cans I have Cam cams first stage and I had the lockout the phasers and it made 350 rear wheel horsepower along with the motion plates delete system

[@briangriffith860]

Helps when you hold your channel locks the right way....

[@cuda4094]

Do you guys have a video with all the new mods including the cam at the drag strip?

[@arcorob]

Question(s) for you - I gather you used the compressed air because you cant crank the engine (manually) to get the valves up , yes? Does the air hold them all up or did you move the air line? Second - have you seen the Lisle 36200 Valve Keeper Remover and Installer tool ? Wonder if it works on a mustang...watched on a Honda and it was awesome....put this in the youtube search box "replace valve stem seals - with cylinder head on" and tell me what you think...would save folks ALOT of time

[@speedacademy]

Correct, the compressed air is one of the best ways to ensure you dont drop a valve into the motor. It pressures the cylinder and holds the vales up. Never seen that tool in action on a Mustang, it could work but we've always trusted the compressed air method.

[@johnbarker5009]

That isn't nearly as bad as I expected.

[@Doodooheadguy-fishing]

Early SA days. Do some more v8 stuff occasionally

[@feellnfroggy]

Ims ure yall figured out by now, you are supposed to prime the oil pump. Otherwise you just ran those bran new cams and lifters dry on first startup.

[@mwhitelaw8569]

How can you not love wedges from Tim's? You sure you two are canadians?

[@austinlarkin5242]

I know this is a few years old at this point, but how much psi of air would you guys recommend using in the spark plug socket to keep the valves up? Thank you!

[@jacchatain554]

Any break in procedure for post install? I've seen comp cam that needed a 15min run in at 2500rpm to properly set and harden the wear surfaces on the cam lobes.

[@wrenchersinc3622]

How long does it take to do this job?

[@Girz0r]

Nice work guys!

[@HvacPanda]

Guessing these are the 127300s? No lockouts/limiters to the phasers to do the 127500s? :( hope it makes some power regardless

[@speedacademy]

Nope, they state no limiters needed.

[@doctorlobsteroctopus]

So you guys work full time for NV now, right? ;) I bet it's really a nice benefit to be able to work in the heated shop, and have a lift too! Great video as always, guys.

where did you buy the spark plug air hose i cant find one? the ones i am finding are 14 and 18mm i was told the 3v is 16mm help me out if you can thanks

[@jaredstafford5565]

I have a question my son's 05 was making some valve spring noise and his car died and won't even turn over is there some kind of sensor stopping it from turning over or did it drop a valve and seize maybe?

[@MrDannyd9]

does the special tool also stop the tensioner from drawing up the chain bc im surprised it didnt get way too tight

YOu have to remove the cams to change the springs so the lifters and rocker arms can be removed at the same time.

Was there a break in period that you had to do that you did not show us? I only ask because there was one for the cams I put in my MR2.

[@speedacademy]

No, hydralic lifters and lash adjusters mean no break in. Start up and go.
