H-260-2 Hydraulic Flat Tappet Camshaft

The Crane Cams 753901 H-260-2 camshaft is engineered for AMC 1964-2005 I-6 engines, including the 199 and 258 cubic inch displacements. Its performance RPM range is between 1200 and 4800, with a recommended cruise RPM of 2200-2600. This camshaft is compatible with fuel injection systems, making it suitable for daily driving, fuel economy optimization, off-road use, towing, and even mild turbocharged applications. The advised compression ratio for optimal performance is between 8.0 to 9.5. Advertised duration is 260 degrees for the intake and 272 degrees for the exhaust, with a valve lift of .456 inches intake and .484 inches exhaust. The lobe separation is set at 112 degrees. Some sources indicate that a timing set from a pre-1998 4.0L engine may be required, as the cam gear and bolt might not be compatible with newer models.
