{"product_id":"cca-camshafts-1005","title":"COMP Cams 12-664-47 - Xtreme Energy 4\/7 Swap 244\/252 Solid Flat Cam for Chevrolet Small Block","description":"\u003cp\u003eFeaturing a quicker valve opening, the Xtreme Energy camshaft profile provides increased responsiveness and more area under the lift curve than older, slower grinds. Designed to increase performance without sacrificing driveability and creature comforts, the Xtreme Energy grind family offers gains in torque and horsepower while still delivering adequate vacuum for power brakes and other vacuum dependent accessories. Xtreme Energy camshafts work great in carbureted applications, but offer the best performance with aftermarket intake manifolds, lower gear ratios, headers and free flowing exhaust.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvertised Exhaust Duration:\u003c\/strong\u003e 290 deg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvertised Intake Duration:\u003c\/strong\u003e 282 deg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmazon ASIN:\u003c\/strong\u003e B001G7CWW0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Lubricant Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBasic Operating RPM Range:\u003c\/strong\u003e 2,400-6,800 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC.A.R.B.
