What Is Your Idle Speed (and camshaft specs)?

It's interesting to see the lobe separation and installed centerlines between various camshafts.

However, I still don't fully understand how the same cam would react with different LSA or installed centerline. Say if my cam has a 113 LSA and the installed centerline was 108 instead of 110. How does that change things.

The higher LSA will provide higher vacuum and smoother idle and will have a broader power curve over a lower LSA cam. The lower LSA will have a choppier idle and typically you can’t run power brakes due to low vacuum. The lower LSA will tend to have a more “peaky” power curve. There are more differences but that’s just what I recall of the top of my head.
