US car companies seem to have this pre-occupation with wide LSA cams in production engines.
The factory cams in the British Leyland engines had 107.5 LSA. The factory performance cams had 102.5 LSA.
A 998 cc Mini engine made 94 hp with one of these cams. That would be 490 hp in a 318 ci engine.
They're balancing a ton of factors. Drivability, emissions, fuel consumption, 300k miles durability expectations, on and on. These are actual inputs to design.
