I believe he was asking if there is a difference in cams. I'm curious about this as well. My car isn't a DD but is on the street occasionally. I'm considering going to a solid this winter. Any and all input would be great.

Listen to people who have solid rollers before you go by the opinions of those who have not run them.
Soild rollers and street engines do go together, BUT....there are things that you need to make sure are right before they will work. The most important thing in my opinion is the lifter/spring combination.....then the oil issue (restrictors or not). Its all in that setup.
I have had 3 solid roller LT1 motors. The first was a 355ci that made 445rw, second was a 396ci that was probably making 480rw (went 127mph NA at the track), and the motor I am currently using to test my theories on some things....and some of my own parts.
I have had 1 lifter fail in that time, and that was because of the valvesprings and lifters being mis-matched (based on what a *professional* engine shop told me to run)...go figure.
Even after the failure, I continue to run solid rollers. Its all in the right parts, and the right parts for your combo dont *have* to cost an arm and a leg.

The intense spring pressures and lack of oiling are what kills them. Extended street use eats up springs too, depending how radical you go with lift and rpms.

As for hydraulic lifters, Comp 875's better known as CompR's are good for 7500 rpm according to Comps Tech Service, Crane also makes a badass HR setup which spins that high. With either setup HR/SR they are both capable systems when setup right.
