Question

What is the better way to degree a cam? The centerline method or intake openning at .050 tappet lift?

I get different readings. Crank tdc'd ,was using a dial indictor on lifter but now borrowing one of those dial indicators that go into the lifter bore from machine shop (said was more accurate).

solid udharold roller. If I use the .050 method I come up with intake openning at 22.5 (spec is 21) btdc which is 1.5* adv. When I use the centerline method I get 101 actual on a 106 spec which is 5* adv. Cam has another 4* built in.


Thanks, Ray

I've always used the intake centerline method.

Thanks Jody! That's what I tought. By using the lift at .050" method(as per lunati website) I had to put the timing set(9 position set)on the 8* adv setting to get it to spec. I mentioned this to my machine shop and he advised me to use the centerline method instead.

Now I have it on the 4*adv timing chain setting and get 105.5 centerline on a 106 card spec.That looks better.

Now I gotta get a new gasket for t-cover LOL!

Thanks again, Ray
