Jonas240z Posted October 10, 2004 Share Posted October 10, 2004 Hello there: I'm currently rebuilding my first engine (I'm really exited about it ) and i got a question about the cylinder head. Ok, i purchased a cam kit from Arizona Z car with specs: .480 lift/ 270 duration, and i went ahead and sent my head to the machine shop to get it reconditioned and also get the cam installed. I got it back but i don't have an idea on how to set the valve lash (cold) because i don't have the spec sheet for the cam. Should i just set it the same as the stock cam (intake .008"/ ex .010")? Or does anyone have an idea on what the settings should be? Thank You! Quote Link to comment Share on other sites More sharing options...
RedNeckZ Posted October 10, 2004 Share Posted October 10, 2004 If the cam came from Motorsport Z, it sounds about right. It is what I have mine set at. On all of my cam spec sheets it says Intake - 008 and Exhaust - 010. Should be a good starting point for you. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted October 11, 2004 Share Posted October 11, 2004 Set em tighter when you do it cold. I'd go .006 and .008 cold, then recheck when warmed up. Also, my cam and the other aftermarket cams that I've seen run a little tighter clearance. Mine is .002 tighter than stock hot, so you might try running a little tighter once you get it running, if it is noisy. Quote Link to comment Share on other sites More sharing options...
Jonas240z Posted October 11, 2004 Author Share Posted October 11, 2004 Thank you all for the help. I was thinking about running them tighter too...like you said jmortensen, but i wasn't sure. Thanks again! Quote Link to comment Share on other sites More sharing options...
Dan Baldwin Posted October 11, 2004 Share Posted October 11, 2004 .008/.010 are cold clearance numbers. I don't think I'd set them tighter than that. Quote Link to comment Share on other sites More sharing options...
