Project Pure Stock Debut

Does the Bullet "blueprint" cam keep factory duration? Is that even published? If it has more duration your RPM range will be higher. On-track testing I have done with both my bone stock virgin LT1 Camaro & TA (not even headers that would effect it) showed quickest ETs (with proper tuning) shifting it at 6000 RPM. I'm not sure what you are seeing on an chassis dyno sheet that tells you the needed stall speed. You do realize, that with an automatic car running a loose converter, the numbers are skewed (out of sync with the torque numbers), right?
