Comp 11-775-8 Grind# CB XR271HR-12
looked up that cam out of curiosity . Is that cam choice real advice for pleasure use ? That's a lotta cam from specs I see

Time tested profile. It will require good exhaust, spring upgrade,and I would do push rods and rockers. A good intake wouldn’t hurt either. 500@5200 or so. I don’t think that’s radical. Any less and the OP won’t notice much difference.

Think you listed wrong part#. The one you listed is a drag race solid roller
Camshafts

COMP Cams Drag Race CB XR271HR-12 Mechanical Roller Camshaft Lift .775"/.748" Duration 324/332 RPM Range 5000-7800

thats full race you need a 3/4

Comp Cams has changed their grind number system I believe. When I was looking for this cam for myself I also came up with the solid roller cam.
This is the cam PH1972 was referring to.
This is a GEN 6 cam but they also make it in Mark IV also.

Hardin/CP Performance also make the almost exact grind for the 454/502/540

I dug out the cam card. Some JEGGS customer’s going to be surprised when this is what shows up for his drag car. Ha

comp cams copy of cranes 731.

Crane 169611 is an option if you have a good exhaust, and at least 9:1. Don't have much info on the engine though
