    Hot Street Cam. If you're looking to get more power out of your SOHC 4.6L then consider a set of Comp Cams XE274H Camshafts. They will give you great mid-range power gains in both horsepower and torque.

    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 3.55 or 3.73 rear gears and a 2000 plus stall speed converter on automatic transmissions. Recommended for use with 4.6 two valve V8 mustangs with intake, exhaust, custom tuned computer, and valve spring upgrades.

    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.

        I have a 2002 Ford Mustang gt Would a stage cam 3 or 4 be a better fit.Im looking for the aggressive sound and still be able to drive around every now and then.

        • Cam selection will rely heavily on modifications already done to your vehicle, as well as it's intended uses. We do not typically recommend the Comp Cams Stage 4 Xtreme Energy XE274H Camshafts unless you have a cold air intake, larger throttle body and intake plenum, long tube headers, and a full exhaust. This cam will build power in the 2000RPM-4000RPM range, so it can be used on the street, however power under 2000RPM will suffer. The Comp Cams Stage 3 Xtreme Energy XE270AH Camshafts may be a better bet for a street car with their 1800RPM-5800RPM range.

        What do i need for these stage 4?

        • The Comp Cams Stage 4 Xtreme Energy XE274H Camshafts are designed for heavily modified vehicles, and work best when installed on cars that have long tubes, off road exhaust, cold air intake, throttle body and intake manifold all replaced. We recommend replacing the springs and retainers with these cams.

        Is it safe to drive the car to a shop to get tuned after the cams are changed

        • Due to the aggressive nature of the Comp Cams Stage 4 Xtreme Energy XE274H Camshafts we recommend not driving the car until it has been tuned, once these are installed.

        Would these be an ideal setup for my 2v? I'm running a 78mm BBK Throttle Body, BBK Cold Air Intake, BBK LongTube Headers, BBK o/r H Pipe, Flowmaster Super 10's, and 3.73 Gears.

        i have a 2003 mustang gt 4.62v would i need to notch the pistons in order to use this camshaft

        • Piston notching is not required, however due to production tolerances in the OEM heads and pistons, we do recommend verifying piston to valve clearance.

            Great rumble, loves high RPMs

            These were the first 'major' upgrade I made to my mustang. It mostly just had easy bolt-on upgrades from the previous owner. The rumble is exactly what I wanted, the shiftknob shakes in my hand and you can see the car shake at idle. Now it turns heads because is obnoxiously red and sounds obnoxiously fast. This was my first time tearing into an engine by myself, but not my first time doing heavy work on a vehicle. The ford modular is pretty forgiving, at no point did I feel like I was in over my head. Highly recommend this cam.

            Great product

            Purchased these for my 2000, 5.4 f150. Tough idle, excellent power, and very noticable torque. Launches hard, even with a 3.31 stock gear setup.

            Awesome product

            The lope and roughness of these cams is ridiculous. I love the sound and have no drivability issues. Daily drive the car with no problems. Picked up an extra 30 or so horses also. The power curve starts a little earlier and lasts through 6200. It pull waaay harder than ever before. Thanks American muscle for another great product!
