Valve/cam specs
I was wondering if anyone has the cam duration(inatake and exhaust), and the valve diameters, intake and exhaust. I tried searching, and all I could find was a thread with valve stem dia. and spring I.D's. Although now that I think of it, it may be printed on the underside of the hood. But I am nowhere near my car right now, so I cannot check.

I don't know how accurate that is, so take it for what it's worth.
I couldn't find anything in the overhaul manual from Nissan.
