"Looking for that radical muscle car idle? Comp Cams has released the 3V modular engine line of rough idle camshafts. The best solution for a mildly modified Mustang is the Thumpr cam set by Comp Cams. Not only can some Mustangs pick up to 25 rwhp at high rpm but you will also get that very choppy muscle car sound and make more low end power than comparable choppy idle cams. This cam set was designed for a rough idle so if that is what you are looking for you will love these cams. This cam set is a NSR grind meaning you do not need to change the valve springs. Because of the Ford Variable Cam Timing these cams require the use of phaser limiters. You can add the phaser limiters at a discounted price using the drop down box above. Also click on the tab above to read about why phaser limiters are needed when choppy idle cams are used."

Gunna cost a lot of money if you want to get camed, but gl if you do.
