Choosing cam for 5.9 magnum

But you could have the same deal if you zero deck the block and/or surface the heads.

Whatever the PO does he should be certain he has a cam ground for a .904 lifter... most of those shelf Comps are not.
Well, I've more than once cut heads .040 and never had a pushrod length issue. But, I really would think with ALL the magnum swaps happening these days, there would be the same amount of choices for "off the shelf" cams that work with stock push rods/rockers as the LA engines. Too bad there isn't....
