Question Grumpy and everyone else at what point of cam size dictate the need for shaft rockers? I obviously know shaft rockers are best but when does say a set of stainless stud rockers need a girdle? And when does the girdle no longer be a viable band aide?
I understand shaft mount is best at keeping geometry where it belongs as there is no swaying tower called a stud. But at what spring pressure or lift? Does rocker ratio effect this? Does pushrod length or diameter? What rpm does it really get hard to control? Is it just a matter of actual camshaft lift. Is there any rules I see guys running both successful but what keeps that success?
