4.6 Mustang 2V Stage 3 Comp Cams XE270AH with SLP Loudmouth 1's 

I appreciate it, buddy!

🐍

Question for you: did you literally replace just the cams? Springs...heads...anything up-top changed out as well?

I replaced the cams, valve springs, retainers, and cam bolt. That is literally everything I replaced.

TheBeastCarson94 did you have to dyno tune your car? I have xe270ah cams installed with 26113 springs I got new bolts and lined up stock gears. now no idle, what's your best take on a reflash for my car because the dollar amount is climbing. any info help thank you for video.

David Redwood I had to get a custom tune for my SCT tuner. Got the tune from BamaPerformance.

Thank you for the response , I will post a vid of my car once I get that tuner or a tune. It's a mineral grey gt '02 and no ptv contact but one thing comp sent me two right hand cams so I had to exchange one cam with a proper left hand.

Thanks, I'll try to make the next one even better.

Nick Yarrington Thank you!!!

Thanks buddy. I like the Flowmaster 10's. I have heard them with a Pypes X-pipe. Sounds beastly.

XxLevegencexX I really appreciate it. The off-road x-pipe will definitely wake up the exhaust. Don't expect to sneak up on anyone with SLP's and an off-road mid pipe. They will hear you a mile away. And with stage 3 I have no problems driving it every single day. It all depends on where you have the idle set at. Mine is at 730 and sounds pretty good. Any lower and it will try to die when you come to a stop. As for power, you lose a little power under 3,500 rpm's but after that the engine really wakes up.

Idk but maybe check some forums

Wondering the same

Say what? Drop a supercharger on it and call it a day. 450 whp all day lol

Awesome!

Much appreciated!

Haha, yes. I have 5% on my GT and cobra. I haven't been pulled over yet.

Lol your lucky. I got pulled over twice for 40% and ended up taking it off completely.

+PowerofMetal247 That sucks. I love having tint on mine. It's look bad without it. Plus I don't like people looking in my car.

Same and people with think twice before picking on you on the road.

+PowerofMetal247 True that. I just roll my windows down when I see cops. It's worked for two years so far.

Honestly, it would probably sound better. I got tired of the LM1's and swapped to their Powerflo muffler. Sounds much more mature now.

Youd need a 2500 stall n either 373 or 410 gears and you would be good

Jim Bob Yes, stock timing marks.

TheBeastCarson94 Did you have to remove the timing cover and put new chains on or anything ?

Jim Bob Yes, you have to remove the timing cover but I used my stock chains. Almost 200k likes on the stock chains and they are still working.

TheBeastCarson94 Awesome I was worried about PTV clearance with the stage 3 cams but now I know I'll be fine if I do it properly.

TheBeastCarson is this an automatic or stick if it’s auto did you change stall converter?

I used stock timing marks. I did the complete job myself. And I also got the whole set of cams, retainers, and valve springs for 60% off because I knew someone who worked at CompCams. So to me it was worth it. Full price? Not to me. I love the sound of the cams still to this day. But the power wasn't a crazy gain. Mainly through 3,500 Rpm's to 5,000 Rpm's is where you feel the power increase. If you have anymore question, please ask.

So by using the stock timing marks you don't need to degree the cams? Did you use the stock cam gears? Thanks for replying! The car does look & sounds amazing! Should upload more videos of it.

Thanks! Yes, I used the stock timing marks and stock cam gears. I have the Romeo block which has the removal cam gears. In order to get the most power out of these cams I would suggest you get it professionally degreed.

Did you tune the car afterwards?

ogcristobal Yes, from BamaPerformance

DA DEPTHS Stock heads. Only thing different are the cams, retainers, beehive springs, and the cam bolt. Everything else is stock.

awesome, thanks and sweet car

DA DEPTHS Thanks, anytime!

CompCam valve springs and retainers. No PTV contact in over 100,000 miles on these cams.

Los Angeles Tv Comp Cam Beehive springs and their retainers

TheBeastCarson94 thanks! Were you ever able to Dyno it? To see the gains after

Los Angeles Tv No, never made it to a dyno unfortunately.

It's the staggered Saleen mustang wheels and tires from americanmuscle. 18x9 in front. 18x10 in back. 275 in front and 285 in back.

Nicholas Degaray Drivability has always been good. I have put like 70,000 miles on these cams and they still drive fine.

TheBeastCarson thanks man!

Randall Smith Stage 3 cams Beehive spring and retainers. That’s it. Stock 03 engine otherwise.

Yes, very little though. And it should sound fine just much quieter than the SLP's. But you'll definitely be able to hear the cams.

+TheBeastCarson94 LMAO guy you have an Off-Road X pipe and SLP loudmouths .... Don't lie to that man saying a little quieter... Depending on his year and how many Cats that alone would kill most of the sound....FYI, I do own a vette, but I'm just a straight sucker for SN95s ... Will be one of my Favorite stangs till I die.

+Texarmageddon It's gonna be a Pypes catted H pipe with 2 high flow cats instead of the 4 stock cats, and the catback. I doubt 2 practically gutted cats will kill the whole sound but we'll see. I've seen some SICK cammed Magnapack vids.

Yes, you can drive it very carefully. The stock tune idle is too low so it will die if you try to idle.

Stock headers.

True that.

2.5inch SLP Loudmouth Exhaust. No converters due to it being a manual transmission.

That's awesome! Sounds like it was a sweet pony. I was going to go vortech before I bought my 2004 cobra. I still daily drive my GT and love every second of it!

Good luck! I hope everything works out smoothly.

Thanks!!

How'd it go because i have the same plan?😆​@@Jkr47nf

Chris Smith You'll wake the dead! Haha

And I don't even care LMFAO

Amen!

It took valve springs for me. Only modifications I did on my 03 Romeo block were cams, springs, and retainers. All from CompCams. Still running strong 100,000 miles later.

Bama Performance tune. Complete dog crap tune but it’s all I had to go with at the time. Most of the chop is going to come from the idle RPM. I believe mine is set around the 750 range. When you have the idle higher it doesn’t chop as hard. Exhaust is: stock manifolds, bbk x pipe, SLO loudmouth 1’s.

@@TheBeastCarson94Thankyou, I appreciate it!

CompCam’s beehive springs. No piston contact after 70,000 miles.

mike james Yes and yes.

@@TheBeastCarson94 Thanks. Did you have to get a tune right away? We're you happy with the sound of the cams? I did the hot rod cams in my 05 get a while back and loved it. Sounded like a big block. But with the tune it ran so rich. They told me that was the way it will be.

mike james I’m not too happy with the Bama tune. I set the idle where I thought it sounded the best. Nice chop for sure.

That was my question as well

Cause my shop told me you can straight swap the stage 2 in without springs and all but i want a more aggressive idle

Swapped the stage 3’s in with stock timing marks with no PTV. Have Compcam’s beehive springs and retainers.

@@TheBeastCarson94 thanks man stage 2's are nice but thats the aggression i want. I have longtubes with a black widow x-pipe and borla ataks all 3in pipe and connections.

@@brandontemples3806 Niceeee

mrjakedasnake813 I may have picked up 30 horsepower. Definitely not anything much more than that with my setup. But I did these cams mostly for the sound.

@@TheBeastCarson94 Is that an automatic or manual? Because im considering buying those cams for my 01 automatic and i wanna know if i need to get a 2000 ish stall converter

mrjakedasnake813 Manual. You’ll need a bigger stall.

@@TheBeastCarson94 alright thanks

On a Romeo block 2v you should have no problem. I’ve put 80,000 miles on these cams with no problems.

@@TheBeastCarson94 ok thanks man

The Romeo block has more clearance in it?

@@byronhamilton6061 I don’t believe so. I remember reading somewhere that the Romeo vs Windsor blocks had different pistons. I can only speak for what I have, which is a 03 Romeo block. No PTV contact here.

Thanks, and no I have not.

I did have it tuned. I had BamaPerformance make a tune for it. I had to data log my car and then send it in. If you have the money to take it to an actual dyno, do it. It won't run without a tune.

4.10's in the rear. I bought a valve spring remover tool made for this engine. It made it a lot easier.

+Oscar Gomez No, just springs and used the stock timing. Everything else is stock.

Cams, retainers, springs, and camshaft bolt was all I had to change.

Yeeeet

No, mine all looked fine when I looked over them. It is a good idea to do while you are already there.

What all did you have to replace anything other than valve springs and retainers?

max moore I always keep up on my comments. When I degreed the cams I used the stock timing marks on the Cam gears and the timing chains. As far as stage 4 cams go, I don't know if you'll be able to run those without PTV contact. With stage 3's I didn't have any PTV contact with the stock timing makes. If you need anymore info let me know.

TheBeastCarson94 okay cool so nothing really needed to be done? Stage 4 isn't that much bigger than stage 3 so I'm hoping it won't be a problem. Did you just get a degreeing kit and do it yourself? Is it hard? A mechanic is doing mine but he works from his house and I really don't have any extra money to get it degreed

max moore I didn't use any tools to degree it. On the stock cam gears there is a little dot on the gear that matches with a dot on the timing chain. Line those up and that's the stock timing marks. Also on the sprockets on the crank have them also. Each chain should have two links with dots on them. You match those dots up with the dots on the cam gear and crank sprocket. That's how I degreed mine.

TheBeastCarson94 awesome thank you so much hope it goes over smoothly this weekend

max moore Good luck!

It’s the cams and exhaust that make it sound so great. Off-road X-pipe really makes it sound mean.

There are stages 1 through 5 from CompCams for the 4.6 engine. Stage 1 having the least amount of power and is said to be just a little different from stock. Then stage 5 is the most aggressive and with the best increase of power. But I believe after stage 3 you are gonna have to get different heads and notched pistons. I was scared that I would have PTV (Piston To Valve) contact with mine but I didn't. That was after reading everywhere that people said that it was impossible to run stage 3 cams on stock heads. They were right to a point, but all I did was install CompCam's beehive springs and I was good to go. Hopefully that answered your question.

+KODstorm21 Stage 3's are awesome.

Ikeem Taylor Is it the entire SLP Loudmouth 1 catback from AmericanMuscle.

nice thanks bro

Nope, sorry.

Adam Gipe No issues with PTV contact.

TheBeastCarson94 Did you take it to a shop and have them degree the cams?

Nope, used stock timing.

285 in the rear and stock injectors.

These are Loudmouth 1's. But Loudmouth 2's are the way to go. These Loudmouth 1's just are too loud and raspy.

Stock heads and NO PTV problems. I was worried about the same thing. Make sure you use Comp's Beehive Springs though.

did you get them degreed?

Patrick Duniphin No

Rollin44s 2003 and yes, I had to get a tune so it would idle.

Only difference between my 2v and a stock one is the XE270AH's, Beehive Springs, and Retainers. Everything else is all stock.

Comp Cams beehive springs and their retainers. You will also need a tune once everything is installed.

Nicholas Cicotte Tell your mechanic he is wrong. I have a completely stock block and pistons. I changed the cams, beehive springs, retainer, and cam bolt. That's it. Used stock timing marks on the crankshaft and cam gears. I've put 20k on these cams and have taken it 6k plenty of times. If you have any questions please ask me. I know there is a lot of debate on this subject.

That is wonderful news! I was hoping i wouldn't have to notch my pistons... I have the Beehive Springs, Retainers, 3.73 gears, 75mm TB, upper plenum, 24lb injectors, longtube headers and catted x-pipe, those should all support the cams nicely? And as well as the Cam bolts, i hear the old cam bolts aren't the right fit, Do you remember where and what cam bolts you got?

Nicholas Cicotte Those should work great with the cams. I got the bolt from AutoZone. I do not remember exactly what size it was. But the stock cam bolt is too small for the CompCams.

TheBeastCarson94 thank you so much for the help! Hopefully I will get these thumping cams in soon!

I never had it dynoed so I couldn’t tell you for sure. It opened it up very much between 3,500-5,500 rpms. Plus the sound is absolutely amazing.

@@TheBeastCarson94 these cams love to rev high u can notice the power at highter rpms

Used the stock timing marks and dropped them in.

The 4.6's sound really good. I any cams sound good. Just depends on what you want out of the cams. Stage 3 lope very well.

I got the beehive springs and retainers. I didn't need the cam gears. Was it worth it for the power? With the deal I got, yes. But I enjoy the sound more than anything else.

+TheBeastCarson94 so I should get the cam gears too cause mine are stock, I really want the stage three. They sound just so amazing and pretty good performance gain.

+Mr. Reyes Good luck, buddy. These 4.6's sound great when cammed.

Awesome!!!

+Nick Esposito Thanks, and no, I just the stock timing marks and kept the stock timing.

+TheBeastCarson94 ok awesome. did you have to do any cylinder head work with these cams? hopefully getting a mustang and want these cams so i was wondering what i needed to support these cams so the engine doesnt go to shit lol

Amen Brother!! All I did was slide and spin, but now the car now has 4.10's with trac lok.

ToTaLChaotic You're right. Even CompCams say that stage 1's are basically stock cams. I would go with stage 3 or 2. Whichever you want. Don't worry about the MPGs because with 4.10's and stage 3's I got 17mpg with mixed city and highway driving, a long with a couple of races.

Okay thanks looks like im going with stage 3, they are more accesible to get it seems then the stage 2 in my area. im only running 3.73's too so that should help.

I installed them. They have nearly 100,000 miles on them with no problems.

Viclaudio gt96 Yes, it will not drive without a tune. It died every time I tried to start mine with the stock tune.

Yeah, make sure you have the cams, beehive springs, retainers, spring compressor, and cam bolt. Other than that just DO NOT drop a keeper. And if you're going to use the stock timing marks make sure you mark them before you loosen the timing chain. If you have any other questions just let me know.

@@TheBeastCarson94 hey do you have a facebook to where i can get ahold of you i have quite a few questions on this

Tj Mccaughan jr I do believe they should work. Only difference is that your 4.6 has pressed on cam gears. You'll have to buy some adjustable cams gears.

Tj Mccaughan jr I don't know if you'll need a new stall or not. I put these cams in my manual transmission mustang. I've heard you'll need at least a 2500+ stall on CompCams website.

TheBeastCarson94 Okay cool, yeah I called the best transmission shop where I live called nobles, and they said that if I run a big cam like that I will have to have a stage 3 shift kit with a 2500 stall I'm just scared about the clearance, I got off the phone with American muscle, and they said I will have to notch my pistons as well? Just kind of confused you know?

Yeah, I was extremely confused too before I started my cam swap. I have put 40,000 miles on these cams and have not had any problem at ALL. I guess Ford must have changed something somewhere in these engines because I'm all stock besides cams, valve springs, retainers and I have NO piston to valve contact.

TheBeastCarson94 I'm actually going to put stage 2 cams in actually, for my build they actually work better But I do thank you for the advice! I'll send you a link to when I get them put in

Nope, no PTV either.

Ray Hoffmann Yes.

Never had it dynoed.

oooo. Any idea what its making? I am rebuilding my 4.6 as we speak and am going with Trick Flow heads, but am still deciding on a cam setup.

I have no idea. I could never get myself to pay to have it actually dynoed and tuned. I had BamaPerformance do a tune for it. I would hope that it's putting around 300 to the wheels.

What is your 0-60?

Low 5's. Depends on if I get traction or not.

Nope, just CompCam beehive springs and their retainers.

Stock Manifolds

charles taylor Yes.

You’re just like me, buddy. Once you do one thing you get hungry for more. Eventually money will hold you back. Loving my GT led to me getting my 04 cobra. My cobra led to me buying my C6 Z06. And now I have three sports cars. 😂 To answer your question. It took me two days ONLY because I lost a valve spring retainer and had to run to a local Pull-A-Part and get another one, otherwise, I would have done it in about eight hours. After I did my cams I rebuild my 8.8 with 4.10’s. I wish I did 3.73’s though. I use mine for a lot of highway driving. Make sure you have the following: -Romeo block. That’s what I have and I have put almost 100,000 miles on these cams. If you have a Windsor block you will have pressed on cam gears and will need to buy aftermarket cam gears. And I can not guarantee you won’t have PTV contact. -CompCam’s cam, beehive springs, retainers, and a new cam bolt If you have anymore questions just let me know.

@@TheBeastCarson94 I have a Romeo block so all good there. I’m going to get a dyno tune following the install to maximize the results, but I’m not sure if I want to pay the extra for the adjustable cam gears. Seems like they are not necessary based off how you did it.... I know very little about timing an engine so I’m not really clear if the adjustable cam gears will allow more power at the dyno... I’m probably overthinking it but if you have any thoughts that would be great. I will also consult with the dyno shop.

@@TheBeastCarson94 I just found out I have a Windsor block. Shoot me haha

@@obran003 Ouch.. I’m pretty sure you’ll just need to get the aftermarket cam gears.

@@TheBeastCarson94 Did you have to upgrade your fuel system at all? Modular Head Shop in Florida says that with the stage 3 cams, they suggest upgrading your injectors to 24lb injectors and 90mm MAF
