Depends on the size of the cam.. Comp Cams says their stage 1 n 2 work fine without a dyno tune but it's always best to be tuned.. Small cams can be driven to the shop, bigger lift cams require additional mods to work n is best you know before going too big..

Stainless Works Headers, OBX, Maximizer's longtubes are available too..

Trickflow

Moser 31-spline axles, factory 3.27's, a Detroit Truetrac, which I recommend over posi. Its pretty predictable when it cuts loose.

They are turndowns just before the axle. I have 2.5" stainless piping for a GM c-body that I'll be fitting in the near future but the Longtubes + X-pipe + Flowmaster 40s combo is hard to beat!

@@mattumber5646 hows the drone im dailying mine?\\ update just got this exact exhaust for mine and it sounds prefect no drone and no clapping noise!!!

Gracias. Good question! Brake upgrades will need to go before more power, so that will be next. The brakes are hilariously bad @ highway speed! :-p

Yes do it up keep the vids coming my dude!

​@Matt Umber You aren't lying. They're ok for every day regular driving. But no way you would want to track it that way.

I'm selling some turbo stuff for a 4.6 2v if you are curious of what lmk

They should don’t think they changed the exhaust only the intake manifold

I'm not sure. The frame was changed a lot in 2003 to make it stiffer for the P71 and Mercury Marauder. I've got a 2000 Grand Marquis, so I'm in the same boat as you, wondering what I can buy and what I would need to have fabricated to turn this beautiful roadburner into the car I know it can be.

No,,,go and do all the easier and cheaper mods 1st

@@tomcatmcgillicutty6913 Agreed. I did this because the heads had to come off to upgrade to 8-thread spark plug wells. I blew out 8 spark plugs and 3 inserts and had had enough. But I wasn't gonna get all this work done w/o getting a cam in it.

Kooks part #12022000. Check out ADTR.net also, they have Stainless Works headers specific for these cars. Mustang headers won't fit, these cars have frame rails you'd have to contend with. The motor was in but the trans was out when we installed them, so access was much easier.

I updated the description, which I would've done even without the profanity! I made the post to share it for enjoyment - goal wasn't big numbers, it was to make it better. I thought it sounded cool so I posted it publicly :-p

@@mattumber5646 makes a dyno video that deals with whp... and you post crank hp numbers... lol wtf?

1. no 2. no. there's also zip ties everywhere. 3. glad you like my boots

@@mattumber5646 we know who thumbsed down this video...lol

They all are expensive now BBK don’t fit the because the routing isn’t the same as the Mustang

Ebay Dude. 96-98 mustang gt long tube for passenger side($200) 2002 expedition long tube headers for driver side.($200)

@@chosenmaster78 really ?! Is this the secret cause I can justify the stainless works headers

@@pimpdaddyslice9889 No Sir,no secret... I just went through about 5 different sets of header combinations, tah find the right combo tah clear... (I already had a few sets from some mustang's, and we did a set of headers on a 02 Expedition 5.4l, and the drivers side cleared on my 02 Merc...) To be specific, the drivers side was an eBay Special pacesetter knock off design,2bolt loose collector flange.

Can also us 2002 ford f150 headers for driver side

If you're installing cams and want the motor to last, you should look into getting the heads rebuilt as well. Performance valve springs/valve seals+adjusters. The main bearings and piston rings aren't common failure points on these motors, so as long as you keep on top of oil changes you should be fine.

If you worried about that many things just leave your car stock

@@mattumber5646 thanks for taking time to reply and inform me about other mods to support the cams

@@crownvictorialifestyle4421 nah buddy you got it wrong, just wanted to know what else could be done to keep the motor safe when installing cams

@@DespisiveDerp start with longtube headers bro, n bolt ons, then, if you want more, cams, TrickFlow 38cc heads n matching cams or just avoid all the lil power adders n get boost, turbo, s/c, or nos n done..

They're charging me $1,200 n i provide new gaskets, tune would cost me here in HTX $500-750.. Hope i helped..

Only worth doing if you do timing chain & oil pump upgrade

@Mike Mike Johnson 25-65whp is what I estimate from untuned to tuned man, oh n make sure cams are degreed to avoid ptvc issues n to make the most hp possible..

@Mike Mike Johnson I say both at the same time..lol Take a look at my P71 n what I'm doing to it.. My best 0-60mph time is 7.5 with Longtubes n Marty tune on my widened 17x12 steelies that weigh 84lbs..lol

@@P71ScrewHead Nice , was that with the cam or did you purchase cam yourself and that 1200 is just installation/labor .....also what shop in H town bro , I'm actually right up the road in College Station, my Vicky needs an attitude adjustment and cam and headers or just cam sounds like the ticket to do it ! Any response from any knowledgeable gear ⚙️ head would truly appreciated, I'm not a noob with mechanical work it anything but I've never opened a block and made UPGRADES either...so again any knowledgeable response would be truly appreciated, I have about 3k budget in total to play with a 2011 crown Victoria police interceptor......shoot me ideas and insights , Wondering what it would cost to just fully stroke this 4.6 2v with ported heads and cam .... I can almost hear hollering through them flowmaster super 10s !!!!!

You can do a lot of things with a little effert. Those headers will fit your 09.

I have an 09 P71 n put Maximizer's longtubes n it does hit the steering shaft, but sound great open..lol Check my channel to see a video of them..

Nope, these were designed for 2003+ Panthers. I did use Stage 8 locking header bolts though, from ADTR.net. kooksheaders.com/headers/long-tube/1-58-x-2-12-ss-headers-2003-2011-crown-victoria-46l-2v

@@mattumber5646 you paid 1200 plus for headers??

@@celeniasanchez2138 About $1k from Summit. Why, would you have welded me a set for cheaper?

I bought O2 Sensor Simulators, which worked to get rid of the check engine light, but the more you mod the more you'll need a tune. A tune will make or break your performance on these things. Palm Beach Dyno hooked me up with a great tune, I highly recommend them!

@@mattumber5646 Now the important question: SCT or HP tuners?
