lunati and crane have all jumped on comps bandwagon with their "voodoo" and "Z" series cams which mimic comps "xtreme" series by utilizing more area under the curve to open the valves sooner. Great concept but these cams are very hard on a poorly prepped valvetrain especially with their tight lobe separation angles. New technology is allowing cam designers to produce flat tappet grinds that are to some extent closely resembling roller tappet grinds. On the same note, roller tappet cams allow designers to create profiles that are just not possible with flat tappet cams. On the other hand Crower has developed a flat tappet grind which looks to be very promising, It's the Crower Ultra Performance Level 4 "288HDP"
234/246 degrees duration @ .050", 288/296 advertised duration, .497/.504" lift @ valve, 112 degree lobe separation angle, 2000-6200 rpm powerband. What's unique about this cam is the duration @ .050" lift and the very wide LSA "112 degree" which accounts for the BROAD powerband. This profile is exactly what "Danger Mouse" is wanting.-- Mad Dog
