Wow, those are some big duration #s. Make sure you've got decent compression, as the cam may bleed some cylinder pressure. Compared to a M4F, the duration on this cam is longer, but valve lift is smaller. I'd really like to know how this cam would run.
M4F is a single pattern cam, 210 dur @ .050" with .420" lift. I assume the Wolverine duration numbers are adv duration, multiply adv duration #s by .85 to get duration at .050".
Its also weird that intake lift and duration are larger than exhaust numbers. Usually its the other way around. This may be an old wierd grind, meant to build cylinder pressure.
