I just found it listed as stage 2 and 3 on different sites. It is listed as having 110 deg lobe separation 214 deg at 50th and 108 deg inlet center 2000 to 5000 rpm and use a 2000 stall on an auto. I would expect that would be a good derivable cam on street, fair but not smooth idle with a ported head, good manifold and headers. Close to what I would pick if I was building a 6. I am not an expert on holden red 6 cams though.
On my red head stroked 308 I went 218 @ 50th with a lobe separation of 110 and an inlet center line of 106.0. I had a lot of people tell me to go bigger but the result was a slightly rough idle and a good derivable car that goes hard for what I have done.
I would not go any bigger if you want to drive it as a cruiser with the occasional run to scare the locals. Different story if you are building an animal though
