Most cams that have that "lope" we all desire are a little tough on the street the lope comes from the lobe seperation and the duration not so much the lift. But you have a roller cam I would suggest looking into the names like comp, crane, lunati, Iskey, abc ford cams etc... They all will give info on idle quality .Stay away from edelbrock they are not made by edelbrock and they have a lot of problems with lifters eating lobes. If you do a cam try to stay under 500 lift even 500 pushes the valve train hard and you can have valve clearence problems. And as I said before the more lope the tougher it is for a daily driver.
