I didn't have the laptop hooked up to see what vacuum I was pulling, but I wouldn't be surprised if it was fairly low because the wind on the highway was stiff, which likely meant my timing was in the mid to high 30's. Again, since I didn't have the laptop open I don't have the AFR either. Cruising around 2,300-2,400rpm.
I don't have the @.050" numbers or necessarily the advertised numbers, just the published numbers by GM, which are likely at .006" lift. 244 duration on the intake and exhaust, 0.438" lift, and 108º LSA. The lobes have a fairly fast rate of opening by design.
