OMM - Depends on the lobe. I'd say you're probably fine but lift numbers are poor indicators of "size". What spring pressures (over the nose) does it require?
I understand completely. I would specify a mild grind and lobe design with street use in mind.
Not looking for max HP but more for that "busy" up on it's tiptoes sound.
Thinking something with around 280 @ .50 duration and gross lift between .580 and .600.
