Dart supplies its own special cam bearings, which feature improved oiling characteristics, as opposed to "off-the-shelf bearings." Once a generous amount of the slippery stuff was applied to the bearings, our Lunati (PN 50256) cam was installed. The specs are: .804-inch lift (intake), .755-inch (exhaust) with a 1.7:1-ratio rocker arm. The duration numbers are aggressive, with 285 degrees duration (at .050-inch tappet lift), and 295 degrees (also at .050) on the exhaust side. Lobe separation is 114 degrees and total advertised duration is a rumpity 326 (intake) and 338 (exhaust).
