turbogrill Posted March 10, 2018 Share Posted March 10, 2018 Hi I bought a cam used without cam card (shabolt m445, same as colt cams 542). What should I set the valve lash to? Stock? I read a post saying that a 0.001" change can affect timing up to 5degrees! I checked the cam timing on cyl #1 intake, and its about right. I only have data floating around on internet so hard to make it exact. Should I atleast make sure that all valves have the exact clearance? What happens if its off? Premature wear? Its for a race engine, someone told me to just make it as tigjt as possible. Not sure about that. Quote Link to comment Share on other sites More sharing options...
NewZed Posted March 10, 2018 Share Posted March 10, 2018 Setting to stock would be the safest. Valve lash gets tighter as engines warm up, so if you go too tight you can warp/burn a valve. Setting tighter is the "racer's edge" method, with racing edge risk. Could be expensive. Quote Link to comment Share on other sites More sharing options...
