Crane 12s should pull a little harder than the Crower stage 2 cams. It has more to do with the lift than the timing. Crane gives more lift, signifigantly moreso on the intake cam. I also noticed that Crane uses different timing. I actually programmed all of the Crane and Crower cam specs into Dyno 2000. Here's a 3 way comparison stock vs Crane #12 vs Crower stage 2. It can be difficult to compare cams without a tool like this cause there are so many variables. You can see that, through the entire range, the Cranes achieve at LEAST 2 percent more VE then the Crowers. Its closer to 5% difference on the lower end.
