Nothing really new here from Vizard IMO, Myself and several others right here on Moparts I believe have been building stroker motors for years with tighter spreads and earlier (100-102) ICLs....and if you look back it's pretty standard practice on most of the EMC style builds that try to get the most power out of their cam/head combos with either rules-limited or self-imposed) RPM ceilings. I think back when I was doing it with Strokers it was to offset the comparatively poor rod ratios and high piston speeds by using up as much of good head flow power potential in as few peak RPM as possible. The EMC's came along judging primarily on the highest "streetable" average 2500-6500 torque curves, so the cam phasing philosophy to get there really seemed to go hand-in-hand, IMO Where the EMC's take it to the extreme is with spring killing lifts and higher rocker ratios than most people would be comfortable running in a "real world" street car. But I concentrate mostly on having great to extremely great head flows in the more moderate, real streetable .300-650" lift ranges and not chase the .750-up lifts. It seems Davids writing at the more extreme limits of such a build, but the principals are essentially the same, and the extreme builds (1.8:1 rockers, etc) will generally have the best brag rights HP numbers too, which I suppose sells more books. (which is what he's probably after).

I think he's just writing about (but hopefully not trying to claim as his own) a trend that's been out there for quite a long while for anyone who cared to see it.
