Thank you for this video. 5 years old, but I was just going nuts looking to see if ANYONE else ever checks this. I have checked the cam on every engine I built but seems like most Datsun engines are just assembled with the marks, never checking them.

I'm changing out the race grind cam in my '72 240Z. I'm going to a more street performance cam with a smoother idle and better vacuum with some more low and mid range torque. I am concerned that the new Comp cam is timed correctly. I will try to verify TDC at the crank timing mark first. Then I'll see that the ICL is correct or pretty close anyway. The timing chain only has 1800 miles on it so it shouldn't need any advancing adjustment on the sprocket. Thanks for the great videos.

Hey Joe, New Subscriber here and no apologies needed for the video of you verifying and validating your L28E Camshaft. Great video, well explained how to obtain the necessary measurements and esp the necessity of repeatability. I too am an engineer (flight test manufacturing engineer) in commercial aviation. I’m curious as to where you acquired the light weight Vlv springs to index your cam. Monkey see Monkey Do principal, you know Thanks again. Nice Shop by the way! Cheers
