Personally (and this is just my humble opinion), any cams that don't require lock outs or limiters aren't worth the time or money.

Comp Cams have a great set of cams that have VCT limiters to keep the cams from slapping around. Those are a great "middle ground". Livernois also sells a set of semi-limiters as well, if you already have a particular set of non-VCT friendly cams in mind.

If you're going to go with cams, I'd go all out, though. VCT is great for driveability, but not for power. Choose the cam that compliments your end goals (N/A, supercharger, turbocharger), choose your power level and streetability, then start looking around for the cams that meet your needs. You can even call Comp and tell them what you want and they should be able to help you spec something out.

I would almost bet you money that the cams you're talking about do not get you 30 RHWP. Just the fact that is says "Requires custom calibration to achieve optimized performance" tells me that much. You can get a good 15-20 RWHP out of an aggressive dyno tune by a professional. Any cam worth 30 HP is going to **** the VCT system off. Period.

If you've ever tuned a vehicle (I do mild tuning myself, but have a pro tune for optimum power on a dyno), you'd know that the PCM will adjust for the air/fuel ratio "skew" that different cams create. You may be able to add a little timing for the cams, but you can do that on a stock engine anyways (the 15-20 HP I mentioned earlier).

Confused. Are you talking about putting these in a Mustang or a truck?

Well, don't get me wrong... they're not bad cams. I just really doubt they'll get you get 30 RWHP on their own merit. The tune will be roughly half of that... and you can get that out of a tune alone.

Do you already have a tuner for your truck? Are you running an aftermarket tune? If you've got the money and are set on these cams, I'd say get the car dyno tuned by a reputable tuner first. Get a before and after to see what the tune alone got you. Then, install the cams and have the same tuner check the air/fuel ratio an optimize (if there anything left to optimize).

Betcha it won't be 30 HP.

So you've already got it tuned up good. Very curious to see what those cams get you.

Do you have the 4.6 or the 5.4?

It's an aftermarket aluminum intake made by MMR specifically for the 5.4L 3v V8. By itself, it took a lot of work to "get along" with the stock cooling system. I had put a lot of time/money into this intake. I wanted a bigger intake that would let me use the stock cooling system, so I swapped to the JPC intake (which required a hood change, too). I got about 18 more HP/TQ out of the JPC, but it was made for the Mustang's cooling system.

The intake comes complete with all the fittings needed to connect to the Mustang's cooling system, so a little work will be needed to make it work with the F150s (not much, but just letting you know what you'll be getting into).

This bolts directly to the heads. No IMRC plates needed (so that'll need to be turned off in the tune and the spark timing moved to the MBT spark table). But it runs great. Nice flow, looks awesome.

The flange is made for the GT500 throttle body, so I'm not sure if you can make that work with your truck. I'm pretty sure you can, though.

I needed to use an alternator from an 04 Crown Vic (non-police model), but I'm including a brand new one. You'll need to rotate the housing 1/3 of the way around. I'm good at it, but I'd advise having an alternator shop do it for you. I'd be surprised if they even charged you for it.

Here are some pics:

and the exhaust forum agree's. i probably will go 2.5 duals first that way i have the sound i need and whatever mod i go i am ready for it. not holding it back! thanks
if you were positive a blower was in the future- defintely go 2.5",if not, stick with 2.25" for best performance

Take a little look at my sig and that will help you with what i've done to the truck so far. First i went to an all-wheel drive dyno and they read very low. Checked out a mustang dyno and was very pleased!

If you're going with a turbo and are not looking for tons of power (and the drivetrain upgrades that come along with said power), then the stock cams work great.


Sorta the reason i am leaning towards a blower.

As for the turbo, im keeping the long tubes i have so the toy car might be a turbo freindly ride.

I have been calling around to some shops that deal with these modular motors and I'm really interested in the blow by racing stage one cams they are billet aluminum they keep your low end ta and have great power over the entire rpm range they also said the frpp cams are a good cam
