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

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

I bought that Lunati grind specifically to avoid machining the valve guides.

I didn't notice in that vid (it's been a while since I've watched it) if he says whether he needed to do that.

I have either running 318 roller or a 100K 5.9 with a slight rod knock to put that cam in, neither of which I'm keen to do a lot of machine work on unless absolutely necessary.
