Camshaft card number question

Syleng1 said

So I just got in my new cam for the 340.

Lunati 10200703
Grind# VH44-VH45-110

So on the cam card it shows 106 centerline makes the cam 4 degrees advanced.
Question is does that mean if the cam is set at 0 the cam is naturally 4 degrees advanced or when I degree the cam I need to set it to 4 degrees advanced or 4 degrees retarded?

Not sure why I’m having a brain fart on this one.
Thanks!

Sorta.....in a perfect world, yeah. The card means it has 4* ground in. So theoretically, if you sling it in dot to dot, it should be on 106. But you have the cam grinder, the cam and crank gears and the keyways in the crank and the cam that all have to coincide with that. That's why when you sling it in dot to dot, there's not a "real big" chance it's gonna be on 106. That's why you always check it with a degree wheel.
