Doesn't need new spring or retainiers. Intake duration @.50" 194 degrees Lift .222(x1.75)= .389 Exhaust duration @.50" 186 degrees Lift .225(1.75) = .383 Stage 3 cams require new spring an retainiers a possibly tuned Intake duration @.50" 216 degrees Lift .225 x1.75 = .394 Exhaust duration .50" 216 degrees Lift .225 x.175= .394 Or crane which this is specd for a n20 cam which I will be spraying Duration. For intake an exahust is 246 Duration @.50 intake an exhaust 204/204 Lobe seperation 112 Gross lift 364/364 These are from the site list which is.

Guest 614Streets Posted February 24, 2009 Report Share Posted February 24, 2009 Duration is how long the valve stays open Lobe seperation angle is the angle between the two lobe centerlines Gross lift is how many thousands of an inch the valve opens Same pattern cams have the same duration at .5 lift and split pattern have different duration at .5 lift TYPICALLY Nitrous cams fall in the 110-113 lsa Turbo cams fall in the 111-114 lsa area Blower cams fall in the 113-114 lsa area NA can fall anywhere lsa but good power is seen 110 and down lsa with N/A The closer to 114-116 lsa the less valve overlap when on the exhaust stroke , exhaust valve closing, and intake valve opening is your overlap. With blowers too much overlap and your boost is "lost" escaping out the overlap cycle. Turbos can benifit from some over lap as they can use the energy for quicker spooling. Nitrous lsa does not need to be quite as high because there is no boost. Quote Link to comment Share on other sites More sharing options...

Guest 614Streets Posted February 24, 2009 Report Share Posted February 24, 2009 If your running nitrous and boost then you dont want much overlap you want to keep that charge in the chamber for power. And this is one of thoose areas where you definately pick up the horn and chat with the cam manufacturer guys and think about custom grinds.

Guest Removed Posted February 24, 2009 Report Share Posted February 24, 2009 it would take to long to help you understand how a cam really works. last custom cam i ordered, i was on the phone for 4 hours or so. Quote Link to comment Share on other sites More sharing options...
Mopar Posted February 25, 2009 Report Share Posted February 25, 2009 As everyone else said, you are better off calling the manufacter. You tell them what you have and want to do, they can reccomend a good cam or custom make you a great cam. Quote Link to comment Share on other sites More sharing options...
