340 cam help needed

the 268 276 stock cam has more duration than the comp 268 chevy cam
the comp has closer lca so it feels stronger down low and midrange
just moving the deck chairs around on the Titanic
the Lunati 268 IS a step up
but since it is a better grind you can use a 262 Lunati and still have more cam without oosing your low end (or even the 256 lunati) (or howard)
