I guess it starts with the 'theory' - as per what Mike was saying about low end vs high end response, then 'trial and error' (albeit the error = poor result, should never make it back to the customer with proper R&D) - all depending on what the car will be used for.

Ultimately, it doesn't actually matter what the cams are, as long as the engine performs as intended.

As Johhny 5 would say - (this thread) needs more input
