S/B rocker arm geometry and contact patch

There are a zillion threads here on “what cam” and if you start searching the forum from day one you notice they are all shelf cams being recommended. When did all the custom cam grinding become all the rage anyway? How did we survive!!!:eek: Just another interesting observation on a slow news day twiddling thumbs!:rolleyes:
I think the custom grinds became the answer when there was so much arguing about which shelf cam would be best. Not which one would work well but there seems to be a need to have the "best". They all work, some just work better. There's way too many variables. That's where the custom cam comes in. Give the variables to the grinder and have them pick one out that will work for your combination.
