I agree with MopaR&D. I think that the reason behind the LS rockers is that they are "free" just like the Viper rods. I'm will to bet these are good used take offs. From that perspective, this setup would be cheaper than a roller rocker mopar specific setup and considerably better than stock setup. Same thing with the Viper rods. Dirt cheap for a good ol boy with connections to a race engine builder, but probably not for someone else trying to reproduce this at home.
