I realize there are several factors involved in selecting a cam and static CR is just one. If a cam manufacturer recommends a CR of 9.5 and your 455 only has 9.1 CR can you use the cam in your build? Are there any problems with this such as lower vacuum and poor throttle response?

Or put another way how close to cam's CR 9.5 must the engine CR be? Ideally they should be the same but is there any lee way? I do not want to over cam.

Thanks,
