Paul, I don't have detailed measurements on the Schneider cams, other than what's necessary to degree them in. Typically they have .300" cam lift (roughly .438" valve lift), and make excellent power with only that much. Recommended lash is either .012" or .014" depending on the specific grind. So far, I think I've had from them:

264 degrees / 110 LSA (torque cam for SUs)
274 degrees / 110 LSA (SP cam for SUs, stock bore D-jet)
274 degrees / 108 LSA (SP cam for big-bore D-jet)
284 degrees / 107 LSA (hot street/rally for big-bore D-jet or Webers)
288 degrees / 109 LSA (B18 vintage racer w/ SUs)

They've all had very wide, flat torque curves (except for the 288 B18, but I don't think they ever got the carbs tuned right) and decent peak numbers -- I tend to go for area under the torque curve rather than peak HP, and they do that.

BTW, the company started in the early '50s as Schneider & Crower, although they soon parted ways -- they've been at this for a while. It's still a small family business.
