The other thing about custom cams is....... not everything needs a custom cam.
Sometimes what’s in the catalog will work just fine.
And....... without testing multiple cams.... who’s to say which is actually the “best”.
I'd say most times, with the exceptions being those instances where a given performance window will be run in. LSA is arrived at by averaging a combination of cam timing events. You can "narrow" the LSA by retarding the intake valve event, or the exhaust valve event, or both. Nevermind a lobe centerline on an asymmetric lobe. It's very complicated, so much so that experimentation is the only way to find out what will work. Ask a successful Stock Eliminator racer how much of the budget is spent on dyno time and camshafts...
