Xfi 260 Camshaft - .522/.525-inch Valve Lift, 208/212-degree Duration At .050-inch Lift, 113-degree Lobe Separation | Enhanced Engine Horsepower And Torque, Oem Computer Compatibility

Comp Cams is now manufacturing three different Cam Shafts for the 5.7 Hemi. Their new XFI (Xtreme Fuel Injection) series of camshafts for Hemi-powered Chrysler vehicles, according to them, "dramatically increase engine horsepower and torque, yet retain compatibility with all OEM vehicle computer systems." The cams are available in three different profiles: XFI 260, 268, and 273. These three new camshafts are application-specific, with designs for street, street performance, and towing. We decided we would take a small step and choose the 260 version of these new cams. The XFI 260 cam features a .522/.525-inch valve lift, with 208/212-degrees of duration at .050-inch lift, and a 113-degree lobe separation. Since we were doing a cam swap, we thought it wise to also install a set of Comp's valvesprings to go along with their cam. Fortunately, these springs are the same as GM's LS-1, and readily available. Yes, it's a fairly small cam, but Comp tells us this particular cam needs no computer modifications. The large XFI 273 cam may require some computer reprogramming.
