    Features & Details

    • Hot Street Cam
    • More Horsepower and Torque
    • Rough Idle
    • For 1996-2004 GT and Bullitt Mustangs
    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 CamsĀ® 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

    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.

    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.

    I have a 03 GT 4.6 SOHC Auto that has 4:10, Prof Product Intake, BBK Plenum, Bigger TB (don't know exact) K N air intake, Bassani Catless X-Pipe that is dumped after the mufflers. It will be tuned with the SCT Hand Tuner. Would I be better off going with the Stage 4 or Stage 3? My only worry is if the Stage 4 will clear okay, I want a loopy good sounding cam.


    • While the Comp Cams Stage 4 Xtreme Energy XE274H Camshafts will install and should have no piston to valve clearance issues, we do recommend checking valve clearance, due to OEM production tolerances in the engine. Additionally, for automatic equipped vehicles we typically recommend a Stage 3 Cam set, for better street manners and driveability.

    I have an 04 gt bbk throttle 75mm cai stock headers o/r xpipe with slp cat back, and 3.73 with a manual trans. Im looking at cams but unsure what stage to get. I want something that as soon as i come to a stop somewhere that i have a very noticeable lope. But as well as performance. Will a stage four or three be a good choice?


    • I would suggest this stage 4 for a heavily modified Mustang. You would likely be better off with a stage 2 or a stage 3 with the modifications listed. However, in terms of what gains you could expect with this, if a customer tuner is involved I would speak with them which camshaft they think they can pull the most out of, relative to your current modifications.

    Are these for npi heads only or pi as well? And no need for piston notching? Thanks


    • The Comp Cams Stage 4 Xtreme Energy XE274H Camshafts will fit all 4.6L 2V heads, both PI and NPI. Piston notching is not required, however due to production tolerances in the OEM heads and pistons, we do recommend verifying piston to valve clearance.

    Could I use the car around town not a daily driver but more than go once in a while to cruise around town with this cam ... Here are my mods I have a 00 mustang gt with 373 gears , bbk. Long tube headers, ported heads, bullitt intake manifold, bbk cold air intake, throttle body spacer 1 inch, sct tuner 93 octane, this car has a 5speed manual. Would this stage 4 cam work good with my setup planning on adding 24 lbs injectors


    • The car would be able to be used around town for cruising purposes, not just on the track. It may be advised with those mods including the cams and the ported heads to jump up the injector size to the 30LB-40LB range.

      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!

      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.
