The cam you have is what many Mopar guys call "a Chevy grind" meaning that it was designed to be used with .842" diameter lifters that Chevys use. A Mopar-specific grind will net you more area under the curve since it takes advantage of the larger .904" diameter lifter. That means more usable torque and power.
If you're going to tear into it, why not get the most power you can? I'd go hydraulic roller if I were you.
