Have a look at the attached Excel model - I built this after igesting the Vizard books as well.
The CR sheet is modeled on my 383 - CR at 10.2 so same as yours.
I've loaded your specs into the Cam sheet - your overlap is only 11 degrees - very small, very mild (try mine at 270/276/110/Avd 4)
The DR sheet then calculates the Dynamic CR based on your engine and Cam specs.
Your DR is very high at 9.5 (put my specs in and you'll get 8.21) - I was looking to get about 8.5 on Vizards advise.
Hope this helps
James
