IM surprised by Richard Holdeners 360 Magnum camshaft swap.......

I'm gonna use this one-

485/485 @1.5 (517@ 1.6) 258/264 ADV 207/[email protected] 112

I wonder what I can expect.
Holdeners cam is only slightly bigger in duration, probably at most something like 10hp less. Think his was 212/218 114 480
