I flew both the -60 and -70 series within the same company during the 80's. In reality, we never differentiated any difference between the two with regards to bank angle for a pod strike. We knew that the CFM -70 series were a bit less forgiving and tended to land in a crab during gusty crosswinds to avoid striking a pod or two (or all four, as has happened).
As previously mentioned, the DC-8 gear is stout, so landing in a crab on a wet or dry runway was a non-event. Just be sure to de-crab prior to the nosewheel touchdown.
BTW, my favorite DC-8 was the -72 (-73 wing, but 30 feet shorter fuselage). Lovely airplane...
