Features & Details

  • Street and Strip
  • More Horsepower and Torque
  • Rough Idle
  • Custom Tuning Required
  • For 1996-2004 GT and Bullitt Mustangs
Street and Strip. If you're looking to get even more power out of your SOHC 4.6L without stepping up to a forced induction set up, then consider a set of Comp Cams XE278AH Camshafts. They will give you great mid to high range power gains in both horsepower and torque making them ideal for street and strip.

Rough Idle. If you love the sound of a rough idle, you won't be disappointed by this cam. Like the muscle cars of yesteryear, this cam yields a sound that will make lesser cars clear a path out of your way at lights.

Adjustable Cam Gears. Maximize the power from your new camshafts with a set of Adjustable Cam Gears, which will allow you the ability to fine tune your camshaft timing - a critical necessity when doing mods that can change your camshaft-to-crankshaft centerline position. Please see drop down option above.

Application. This SOHC Camshaft is designed for 1996-2004 4.6L two valve V8 Mustangs with 3.73 or steeper rear gears and a 2400 plus stall speed converter on automatic transmissions. Intake, exhaust, custom tuning and valve spring upgrades are required.

Technical Note: Comp Cams are designed for modified cars that include upgraded valve springs for clearance related issues. It is recommended to use COMP Cams® 26113 Valve Springs for proper fitment, see drop down option above. Combine the valve springs with a new set of valve spring steel retainers to handle the higher pressures developed by the springs.

Fitment: 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

What all modifications to the engine will these cams require? Will they go directly in a stock 99 GT without having to change the heads and so on

Jc

  • These cams will fit a 99 GT motor. We would recommend the following maintenance items be changed when you have have the timing cover off. New timing chains, chain guides, as well as a crank sprocket. Also be sure to check you hydraulic chain tensioners and lifters to ensure they are in good function order. Another worthwhile part to consider changing to ensure the motor's reliability for years to come is the Ford Performance SVT 4V Modular Rocker Arm/Follower Set item #50318. Of course the normally recommended upgrades such as cam gears, valve springs, and valve spring retainers are a required upgrade for larger lift cams. All of the aforementioned modifications will need to be professionally installed, and the cam's will need to be professionally timed/degreed to ensure there is no PTV clearance issues. I would however like to guide you maybe in a different direction for cam selection. Reason for that is that a Stage 5 cam on a stock 1999 GT will not be the best cam to go with unless the vehicle is heavily modified. If the engine is stock with little to no bolt on modifications, I would suggest a Stage 2 cam (also offered by Comp Cams) item #30158. If too large of a cam is used, it will surpass the performance capabilities of the motor which will result in poor "off the line" performance and result in poor drivability.

I have an 00 GT with 04 cobra supercharger, will this be a simple install or I need to keep tuning in mind as well!?

StreetKing

  • The Comp Cams Stage 5 Xtreme Energy XE278AH Camshafts will install like a normal camshaft, and this will require a tune. Since this is a quite a unique build with the supercharger from a Cobra, I would highly recommend speaking with your tuner to make sure this is something that can be compensated for in the tune.

  • The Comp Cams Stage 5 Xtreme Energy XE278AH Camshaft is one of the biggest cam that can be used, however, you will always want to check piston-to-valve clearance when working with valve-train components.

Do these have to be degreed?

Ikeem

  • Hi, These Comp Cams Stage 5 Xtreme Energy XE278AH Camshafts should be degreed this is the only way you will know if the rise and fall of the pistons properly matches the opening and closing of the valves, so the engine will run properly. A few degrees of misalignment can affect the engine's operation dramatically.

Clearance and diffrence I HAVE A 2 PART QUESTION FIRST ..DO I NEED NOTCHED PISTONS TO RUN THIS CAM..AND WHATS THE MAJOR DIFFRENCE IF ANY BETWEEN STAGE 4 & 5 CAM. THANKS ANY INFOS GREATLY APPRECIATED.

DREADSAW

  • With all camshafts, we do recommend measuring piston to valve clearances due to different tolerances in engines. The camshaft specification change slightly: The stage 5 specs are: Duration: 278(intake),282(exhaust) Duration @ .050" Lift: 242(intake),246(exhaust) Valve Lift: 0.55(intake), 0.55(exhaust) Lobe Lift: 0.3(intake),0.3(exhaust) The stage 4 specs are: Duration: 274(intake), 278(exhaust) Duration @ .050" Lift: 236(intake), 240(exhaust) Valve Lift: 0.5(intake), 0.5(exhaust) Lobe Lift: 0.274(intake),0.274(exhaust) There is also some differences in valve timing as well.

    Real power

    If your looking for real power and a good sound then this is your camshaft. I thought I had to do a lot of upgrade to run it nope but I do suggest if you have full Bolton's or are going full Bolton's I highly recommend this cam .
