MP 292H cam too big?

You have to look close at the details... The intake closing point should be 74° ABDC. The intake closing point at .050 is 37.5°. So you should be using 37.5+15= 52.5. Try that one...

Just to add... the calculated dynamic compression goes DOWN with a larger cam, not up. So if this cam was too large (I don't think it is...) then the dynamic would be low (in the 7s), not high (in the 9s).
