I had the 276HR on a 110 LSA in the L98 with a HSR intake and AFR 195's. Pulled to 6k all day. Was a nice setup.

Re: cam for hsr
I ran the LT4 hot cam in a 355 with trick flow heads , flat tops and a single plane. Made 320 hp on a mustang dyno with a conservative safe tune. I think the XE276HR is a good choice, better than the hot cam. Idle was noticed but not unruly or really lumpy.
