Just wondering if anybody here has any real world experience and knowledge of roller cams vs hydraulic cams in the context of Holden V8's (5L in particular).
I'm aware of the benefits of a roller cam, but I'm just a little unsure of how well the specs of a roller cam translate to a flat tappet cam. For example, for a cam with the same specs in both types, could similar power and driveability be expected? For example, comparing the crane 276 flat tappet to the crane compucam 2030. The suggested basic rpm ranges suggest that there's a fair bit of difference in torque/driveability between the two.
Here are the specs for the compucam 2030.

Rev range 1600-5000
Here are the specs for the 276.

Rev Range 1800-4500
The basic question is, will the 2030 be a better cam for the street and perhaps outperform the 276?
