Can anybody tell me what's wrong with my cam card. I think they sent me the wrong one. When you run the numbers through a centerline calculator they don't add up.

What specifically dosen't add up? Only numbers on the cam card that would be pertinent is the duration. I get 23+180+67=270. These number are the same for both intake & exhaust. ???

Sorry I should of been more specific. When I try to degree my cams I can't ever get 23 @ .050 it's more like 2 degrees and I don't have enough adjustment on my adjustable cam gears to make up the difference. It's the same for 67 it's more like 28 degrees @ .050. Wouldn't the centerline be different than 109
23+67+180=270÷2=135 centerline not 109?

I don't think your cam card is showing duration @ .05. It has strikeouts under this column. I think the 270° is advertised duration. I believe 109° is Lobe Center, simply the distance between the peak opening points on the Intake and Exhaust lobes.

So how am I suppose to degree the cams based off the cam card?

Watch this video from the Master, Jafro.

I've already watched it several times. His cam card makes more sense and he has better specs on his cam card.
