  • Great Mid-Range Gains.
  • Big Loping Idle.
  • Strong Vacuum.
  • Streetable Cam Design.
Big Power Gains. If you're ready to take the next step in power mods but don't want to go with a forced-induction setup, Comp Cams Stage III Xtreme Energy Camshafts are a great addition to your Pony. They will give you great mid-range power gains in horsepower and torque. They are best suited to Mustangs with Performance Improvement Heads.

Streetable. This cam balances an aggressive profile with street driveability. When tuned, you'll still be able to drive your Pony around town to show it off to your admiring (or envious) friends and onlookers alike - and with a big sound even at idle this cam is guaranteed to turn heads.

Deep, Loping Idle. If you love the sound of a deep, loping 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 steeper 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: The stage III 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

    All the dyno charts I had seen on these cams showed good power throughout but not the highest total HP gain. I didn\'t want to lose bottom end so I selected these cams. I had the car dyno\'d before and after and before the cams the car made 404 rwhp and 398 tq, after 492 rwhp and 430 tq!! The numbers don\'t lie, that\'s an awesome gain for the money! However, the car made much better power before 4500 rpm before the cams. The car really wakes up at 4500. Although Comp recommends 3.55 gears (which is what I have), I would go with 3.73s because even my supercharged 2V won\'t get out of it\'s own way on the highway in 5th gear. You can\'t compare the idle with these cams though, absolutely awesome! Car sounds super mean!

    For my 2003 GT these cams are great!!! Note: Upgrade the valve springs, buy 2 stock crank shaft bolts to attach the cam shaft gears, yes Ford crank shaft bolts 12mm by 1.5 / 44mm long, and YES will need a tune or need a tuner with some knowledge how to use it. Other than that very peppy over stock PI and I am running stock injectors.

    great bang for the buck

    these are a amazing buy for the price. you cant beat it. although they are a pain in the to install the reward is well worth it. I love the great deep exhaust note i have on my car. haven't gotten it tuned yet so i havent seen the best of the power gains but so far it is noticeable difference in the car. would tell anyone thinking about getting these to buy them in a second youll be happy you did

    I have these cams in my 03 gt, love the cam sound but the best part is hitting them higher rpm's and feeling the cams put you back in the seat again. Im running the stock intake but 24lbs injectors with the 4.10 gears pushing 325rwhp all motor no power adders.. highly recommend these cams great buy great power..

    i installed these cams on my 97 gt and i have to say they are pretty amazing...the car is louder and alot more power in the higher rpms...the only problems i encountered was that the idle is very very low so if im stopped at a red light i have to be constently be pressing the gas to keep the idle up or it will stall out but thats without the custom tune so that might be y but dont let that stop you from bjying this product is still amazing!!! good job american muscle you guys have the best custumer service and for 580 its worth it

    stage 2

    These cams are great but one thing you need to know. The stock cam gears are pressed on to the stock cams so you have to buy a new set of cam gears which are around $350. But the good thing is that the comp cams bolt on to the new cam gears.

    I paid to have it installed. They did it quick with no issues. I still have not dyno tuned it but it is nothing less than awesome sounds amazing, lost low end torque. But gained everywhere else! Would recommend to anyone.

    Great hp gain

    these cams are a great modification to an engine, but there will not be a big noticable gain unless you upgrade other aspects of the engine, injectors (im running 30lbs), cold air intake, throttle body(im running a 75mm), ignition, plug wires, and the computer MUST have a tune to advance the timing, air to fuel ration...ect,you would have to buy a tuner and do it yourself or take it to a performance shop but that smore pricey...good luck with your stang :)

    sweet cams

    Put these cams in my port and polished PI heads allong with polished valves and stronger valve springs. Did the PI swap in my 96 GT and got it tuned by Dez Racing. The cams sound awsome! Not over done but very well pernounced sound. Nice power gains above 2,500 RPM all the way up. Highly recomended.

    this was a great buy

    this is a great cam and good sounding the one thing i can help out with is the correct item #'s for the parts you will need if you are doing a engine build like me cause american muscles are old. the cam bolts (ford part #) F1AZ6A340A and the washers are F1AZ6278A as for the spacers i got from summit racing they sell them for 20 bucks. but if your looking for something to make your pony sound nice and its oyur dd i would definatly buy these for some good street use.
