Cam degree.

I'm using the instructions that came with the cam. When you specify "centerline," are you referring to the "installed center line" noted at the top of my cam card?

That's not instructions, man. That just the cam card. I tried to tell you to use the intake center line method. It's much easier than whatever it is you're trying to do.

That said.....keep this in mind. If that's a Rollmaster set, remember, I had one that the crank gear was 100% marked incorrectly.

But don't concentrate on that YET. Use the intake center line method and see how it comes out.
