The dimension of sound you have added to your car is what makes the hair on my arm stand up. I, quite frankly, wouldn't care if it didn't make any extra horsepower, the symphony of sound it cranks out is worth the price of admission. Great work, Sir!!

[@Compcams1976]

Thanks so much - we're glad you liked it!

[@megakoolj-3166]

I agree 👍🏻

[@ghunt81]

Thumbs up for showing the install on this video, getting ready to do cams myself and this was the method I wanted to use (no spring compressor), thanks!!!

[@Compcams1976]

+ghunt81 Awesome -- let us know how it goes!

[@ghunt81]

+COMP Cams Finished it a couple days ago-ran into a few small issues but the car is done and running!

[@Compcams1976]

ghunt81 Glad we could help! Congrats on getting the car finished!

[@Balrog124]

+ghunt81 Can I ask what the issues were? I am about to try to install the cams myself and any advice would be greatly appeciated thanks

[@ghunt81]

+Betty Issue I had was I didn't pay enough attention to how many lobes were engaging valves when I started to take the cams out. There is a position you can put the engine in where most of the lobes aren't engaging, it will be a slightly different position for both sides but that's where you will want it when you do this method. If it's not in that position it makes it really difficult to get the cams back in. You also have to pay attention to how the cam is centered in the bearings and over the followers, if it isn't you won't be able to get the front cam cap back on (that's where the thrust bearing is)

[@mikeray2782]

Pro Dyno is the only ones i trust to do mods on my Mustang

[@kingssuck06]

These are cams for sound, they use the stock valve springs, they have other cams that use the stock springs that give 30+. These are for sound

[@Compcams1976]

Thanks for watching, Tim! We're glad you found it informative and enjoy the new cams!

[@topgearulz]

i was expecting at least 60-70whp with the cam and tune! 11wph can come from an intake and header back

[@kingtuckgesus8879]

Hell just the intake will get you that or a tune with no mods

[@MrSandhu11]

You have no idea lol

[@stickyicky2858]

@@MrSandhu11 well I do considering my car a tune alone got me 12hp intake and throttlebody was another 27hp full exaughst setup was another 18 HP and then I did 410 gears a intake manifold and pulleys the car fbo makes 380 to the wheel boost is next already ordered my eagle forged Pistons and rods and already have my new fuel pump and I'd 1000s just waiting on my back ordered hellion kit them I'll be around 800whp

[@misterbulger]

Ive been holding out for the right 5.0 but the 4.6s are starting to grow on me now...

[@Compcams1976]

Yes, at about 2:29 they talk about this. Basically, they don't let the chain move off of the sprocket, then install the new cam the same way the old one came out. The shop that did this install had done it many times before, so they really had the procedure down as simple as possible. Thanks for watching!

[@N-Scale]

Thank you all so much for the wonderful install tutorial !!! Sound is fantastic!

[@sgtbigdawg8363]

I'll be going with the FRRP cams and heads myself and later an Edlebrock charger ! The FRRP parts have been tested specifically for the Mustang GT 4.6L, 3V motors so you will get the most bang for the buck.

[@Compcams1976]

We're happy to hear that! Thanks for watching!

[@Compcams1976]

Hi Mike, Yes you do need the phaser limiter kit part# 5449 with the Thumpr Cam. Thanks for asking.

[@Compcams1976]

This project was actually done at Pro-Dyno, your best bet would be to contact Pro-Dyno.net for any specifics. Thank you.

[@abridges1992]

NO ONE DOES IT BETTER THAN DAN @ PRO DYNO!!!

[@Compcams1976]

This shop is in Fort Mill, SC - outside of Charlotte. Thank you.

[@Compcams1976]

It depends a bit on your application, but they retail for $200 - $300. You can check out compcams.com for exact specs. Thanks so much, glad you liked the video!

[@Compcams1976]

If you check with a few local auto parts stores in your area you should be able to find one. The exact wedge you will need may depend on your application. Hope this helps.

[@sabrinakunkler1059]

Some require a tune and phasers others have no requirement and fit right on with factory parts depends what u want to really get in to

[@johngrande1087]

OK bro thanks for letting me know . He said don't put the lube on the lobes because it could cause damage . Only put it on the baerings.

[@Compcams1976]

Thanks for watching the video! Your best bet is to contact our CAM HELP line at 1.800.999.0853. The techs will have some questions about your engine and overall setup, and will then be able to help you pick out the best cam for your 5.0.

[@oldmusher]

Oh, for sure. For the street especially, I think automatics make the car a lot less versatile. For a drag race only car, a built automatic can be the key to consistency, but I consider a stick to be substantially more fun. You can tailor your "stall speed" with your clutch leg. Takes experience, though, and skill, and that scares many away.

[@Compcams1976]

The work on this car was actually done at Pro-Dyno, so your best bet is to contact them at pro-dyno.net for any specifics. Thanks!

[@DDR233]

Why didn't you put in the phaser limiters? Are you not concerned with degree issues and valves hitting the piston with variable valve timing??

[@joshcates6987]

I’m wondering the same thing

[@TheZman77]

dang! i was honestly pretty scared to tackle this install, but i think I may just have to do it now!

[@KartKing4ever]

The reason you need to compress the springs is so you don't drop the valve. You don't need to do this but if you do manage to drop the valve and not catch it, chances are you'll end up blowing out the piston and ruining that valve cover if you don't catch it.

[@oldmusher]

You are right about the need for headers and intake changes. Plus, the 11 horse is at full throttle and rpm. I'm guessing there is an improvement all through the rpm range, which is actually what you will feel. It's not like you only get 11 on top and business as usual at every other rpm level. But...the automatic (yuk) does not effect horsepower. If you pull the slush box and put in a 6 speed...do you think the power goes up? No. The base test was with the same car/transmission!

[@Compcams1976]

@Kevs08stang Yes, it does require the the 5449 phaser limiter kit and custom ecu tuning.

[@Compcams1976]

COMP Cams recommends changing the lifters, timing chain, springs and inspecting all other parts before reinstalling.

[@ProjectMercuryMarauder]

What would be a comparable camshaft set up for a 4.6l 4v (the DOHC engines)? It’s for a Marauder so it’s got a higher stall torque converter and a better gear low end gear ratio over that of a typical mustang GT.

[@johngrande1087]

I was answering the other person that asked about break in procedure that's all.

[@kanervatie]

Love the sound.

[@Compcams1976]

Thanks! We're happy to hear it!

[@Compcams1976]

@planefloat Unfortunately there are too many variables (engine combination, weather, testing standards) that effect emissions testing. Therefore we are unable to certify that any aftermarket cam will pass your local emissions testing.

[@rdsimmonds]

If you're talking about the one I just looked up, that's not a stock or 'sealed' engine.

[@Compcams1976]

Yes, we do! You can check out options on the COMP Cams website, or feel free to call 1.800.999.0853 and one of our techs will be glad to help you out. Thanks for your interest.

[@Compcams1976]

This work was done at Pro Dyno, so your best bet would be contact the company at pro-dyno.net for specifics. Thanks!

[@talinegle6182]

do you need to have the crankshaft in a certain position when removing the cam?

[@fwh79FOXR6]

Talin Egle: 0 degrees ATDC on the number one cylinder is probably a good idea.

[@ComprehendTheTruth]

honestly dude its not to late to learn...when I had my honda i didnt kno sheeetttt just like mufflers and intakes, then i got a mazdaspeed 3 and i know like intake, turbo inlet, turbo manifold, downpipe, catback, intercoolers, blow off valve, wastegate, oil catch can, springs, slotted rottors, all kinds of things!! and ive only had the car for 3 MONTHS! haha still a lot to learn but i learned all that on my own just upgrading my car piece by piece and research

[@cali2170]

I am in the process of swapping to the mutha thumpa cam in my 08 gt, according to the ford racing instructions on getting the motor to tdc my #5 exhaust lobes should be coming off their stroke, but they're not when the timing mark is at the said "1o'clock" position

[@primalscream46]

@p4ndiamond ha, i'm a ford mechanic, and if you have never used one, try it, you'll never look back.

[@johngrande1087]

That is not what i asked you . You replied about putting motro oil on cam . I asked should you put the engine at top dead center before starting . Thank JOHN

[@bigjohnstud4200]

I don't work for the company, but yes they do. The only difference between the earlier mod and this one is the earlier is 2v rather than 3.

[@hellfire08]

i'm in the middle of this job and I need help! 07 mustang gt, this engine has cam bearings! how come I dont see cam bearings in any of these videos?? what's going on? I tried to install the new cams with the existing cam bearings and the engine wont spin.

[@Compcams1976]

@planefloat Each cam is designed for a specific reason, it's hard to make a cam that's going to produce monster power that's not going to affect fuel mileage in some way or form. As for your question with drivability, there are many cars using these cams that are daily driven. Give our CAM HELP tech staff a call (1-8000-999-0853) or email if you have specific questions related to your application - they'll be glad to get you pointed in the right direction. Thanks for your interest in COMP Cams.

[@ROWB0AT]

Power gained throughout the curve is more valuable to most street/occasional strip drivers, even if they don't realize it. I'd rather have a flat curve than play who has the bigger number.

[@eshkakogan75]

I like to rile up you Ford guys is all, i work a few die hards, always sinking a shit ton of money into their Stangs and then never drive em. lol . Its a nice ride man. I like my Imp cuz its the fastest grocery getter ever produced. Cheers

[@MrKaiju22]

I know transmissions dont add or remove hp, but it does affect how much u plant to the wheels. an auto will have a little more driveline loss than a manual from the factory.

[@Typhlosion100]

Im going to be installing the stage 2 cams on my 02 mustang gt.

[@jacobhousley9790]

Does the engine need to be in a certain position before you start?

[@hebeb394]

just go with a ford numbered cam man... like b303, e303, f303 there are plenty of videos on youtube of them, i personally suggest a b303 or e303 with 1.7 roller rockers they wont dissapoint... if you want to go bigger and still reliable then get some gt40 heads and almost any aftermarket intake to go with the cam youd be happy with it

[@andrewmapes8205]

I want to put a set of these in my 99 gt 2v. I have a 347 bored and stroked Windsor block, PI ported and polished heads, along with trick flow track heat intake manifold & plenums. BBK 78mm throttle body and BBK 70mm MAF. What cams would be a good choice for me? I really don't want to do the rollers, rockers and springs if I don't have to.

[@oscarncandi2013]

damn that sound is so sick

[@jayjohnson3645]

Do you have a part # for this one? Currently, they have one but state it's requires cam limiters.

[@warlock3055]

Question, after I install this cam, do I have to have a tune before I start and can drive it?

[@cheeko_914]

Yes you do

[@precisiont5188]

Where can I purchase the new cams for my 2014 Mustang V6 3.7? Please provide a link.

[@kayladeremer1828]

By chance do you have the link to these exact cams I would love to order some like these Where I don’t have to change anything other than the cam

[@TimothyIpmanchilds]

so if I do this method I don't have to turn a crank back and forth from 6 and 12 like most of these video show

[@MrStangus1]

Does the 127050 kit need the phaser limiter kit? Also what do they sound like? There is not a video or anything in existence and I don't know what to compare them to. I just know they are "mild".

[@ascaniboy]

Where is the spacer and washer the comp cams manual recommends? F3AZ-6265-A & F1AZ-6278-A

[@xx7legion7xx99]

Hahaha, because of this video i made a nice chunk of change today because some dope messed up the timing Marks. Had to do a tear down and line everything back up.

[@davidmartin2231]

Did you have to set the engine at the one o' clock position?

[@James-wg5pe]

Can I replace the rocker arms and lash adjusters When I do this swap?like do they just pull out with no tool?

[@MrKaiju22]

11hp with that intake and probably factory exhaust manifolds sounds about right for a stage 1 cam.

[@oldmusher]

11 hp doesn't sound like much for the price. But, he says that the stock intake has airflow restrictions. New cam profiles mean that changes to the rest of the setup will be required to see full advantage. 11 horse for the cams.+15 horse for headers, better pipes and mufflers. 15 for ignition improvements (chip, etc.). 10 more with better intake flow Do them all at once and boom! "Tuning" is the weak point of fuel injected engines. At full throttle, carburetors rule. Cheaply.

[@harveyhoward9417]

Is it safe to start the car before installing the tune to check for normal operation?

[@planefloat]

In states that have emissions testing, does the cam swap affect the amount of measured emissions? Great video, thanks!......Art

[@N-Scale]

I thought these neded a Phaser Limiter??

[@Compcams1976]

We understand. You can also feel free to email [e-mail] and those guys will also be happy to assist you. Thanks!

[@CarportChaos]

i noticed he didnt put limiters or lockouts in the phasers, what up with that?

[@wavyybased1820]

Jake Buchanan you don’t need it for the stage 1.. you need it for mutha thumpers which is stage 2.

[@imsohigh314]

you didnt have to intall phaser limiters >?

[@r8r4life36]

I've got a 4.6..mustang roush RTC..I'm gonna get the mutha thumpers..anyone know the price range it cost to have these installed?

[@Compcams1976]

Very cool! Let us know how it goes!

[@isaackellerman3006]

That thing looks just like my car apart from the center lights

[@MoToGT05]

is there a link to the full video of this install? not just bits and pieces. gonna do this myself this weekend and just want something to go by so i can make sure i keep the engine in time.

[@strokedmustang66]

Is there a part number somewhere I don't see?

[@demonracer6]

nope, 5.7 hasnt change in how many years of making it? the 350 went to 346 for the LS1 so it went down in displacement, and still owned the 4.6.....i think that would be new tech...and considering the new 5.0 has to have 32 valves to beat chevy...pushrod>modular

[@twistymcslide2]

numbers would be higher if there was a tune also , 12.9/13.0 can be leaned, probably net another 10 whp , prior to exhaust etc too id think . not to shabby

[@joshcates6987]

I noticed y’all didn’t use the limiters?

[@eddiegonzalez8675]

Is 11 hp really all that is gained? Was this with the tune? Man I really wanted this done but it sounds like it’s not worth it.

[@planefloat]

I realize the huge expense getting a C.A.R.B. approval. I'm in FL and tailpipe emissions inspection have been discontinued for years. Are there any downsides to the conversion i.e. decreased drivability, fuel mileage, cat converter overheating?

[@Typhlosion100]

I will upload a video of it when I do!

[@DrummerPro13]

You don't need to move the timing when installing this cams?

[@Compcams1976]

It's never too late to learn!

[@bigholmes95]

Hey sweet pony! I was thinking about doing cams on my 06 GT but I have a question. These 4.6's don't have a lot of bottom end torque due to the size so I'm curious if you noticed any loss in bottom end (lower rpm) grunt after the cams swap. Did your mileage fall off the chart? What changes other than top end pull did you notice in your car after the swap? Any info is appreciated!! FYI. I've already done full Borla header back exhaust,Bama tune,BBK open element air filter. Cams are the next step. Thanks!! Reply ·

[@Compcams1976]

The reports we have received from customers are very positive, there may be just a little loss of low-end, off-idle torque, but the mi-range and top-end is great. Mileage doesn't really change too much if any. You also might want to check with the guys that did the cam swap.Their website is: www.pro-dyno.net/ Thanks for your interest, hope this helps!

[@Hudbudd]

I'm sold. These are going in my expedition

[@driftcat7076]

I hope you didn't lmao

[@Zenki240sxse]

Sweet caliper covers...

[@robertswift6101]

i wonder how much this would cost to have them or someone do it?

[@lordXguru]

I've been told that if you change the cams that you must also degree them, but in all the videos I see they skip this step.why?

[@Compcams1976]

We do recommend degreeing cams, but many customers skip this step, especially if a factory, non-adjustable timing set is used. Hope this helps, thanks for watching!

[@kayladeremer1828]

Or a part # thank you!!!

[@johngrande1087]

Do you have to put the engine on TDC or you don't do that either thanks JohN

[@wingz350]

Can you make custom grind thumpr cams for the earlier mod motors? I want some for my 04 crown vic

[@disabledvet420]

oh i see it, other comment below.........so this DOES need a tune and a phase limiter kit

[@marine0331inf]

I have a question. I have the xe270ah cams for my car a 2001 mustang gt. The old shop that installed it said that I did not need the springs for the cams. That was a few years ago now. Since then I have had it tuned and runs fine.

[@Compcams1976]

The XE270AH cams do need a valve spring upgrade for the best performance. It appears the factory springs can handle the lift of the cams, but they are a bit too light on pressure. Our 26113-16 valve springs have more pressure to keep the valve train stable in the upper RPMs,which is where more power is typically made. They are also more durable in the long run. The new springs do require new spring retainers part# 792-16. Hope this helps - thank you.

[@marine0331inf]

COMP Cams good info. Looks.like ill get the spring upgrade. I always felt i should be making more hp than what I have made so far.

[@YoungSlaughterAka]

What is the best idle speed for these after installing them

[@johngrande1087]

Do you know it it's better to put the motor on TDC i noticed he didn't do that .thanks

[@wackoman544]

john grande no need to put the motor on TDC if the sprockets and chain don’t move, the cam can only go back in the same orientation it came out. So if it came out properly timed it will go back in properly timed

[@Compcams1976]

Thanks for watching!

[@ralphieb87]

i have a question. where the phase limiter kit installed? im asking because when you buy this kit its says that its required to install these items. i wanna do this upgrade, but i want to make sure i have all i need to do this.

[@FrancescoMustangGT]

Hi I would like to replace the cams, the rocker arms and the lift adjuster,in the same time what is the best way ? Thanks so much Francesco 2006 mustang GT

[@cruzanity7478]

Francesco 2006 Mustang GT 1st do the Ford Performance rocker arms & adjuster kit, it is around $400-$450 plus installation or if you know how to do it, then look for the cams that do not require any other aftermarket springs such as these ($700-$1,200).

[@FrancescoMustangGT]

I ask how to replace everything, at the same time, what is the procedure? thanks you so much

[@alidashti223]

Do you guys make cams for 2005-2010 V6 mustang 4.0L?

[@alvvpahh1719]

These is kinda the same as a 2001 f150 4.6 right

[@DDR233]

Is this a similar install to the 4.6 3v comp 2 nsr cams?
