The springs are not the issue here. BTW guys, beehives in a cam only setup are better than duals. They have better harmonic control.
As far as power, what was your base numbers (before cam)? And was that on the same dyno? or are you comparing 2 different ones?
That cam is capable of a healthy 35 to 40 rwhp gain.

 

Yea yea two days later... Update.
And predator could be correct on the spring. But toward predator, the numbers were from the same shop same dyno as posted by OP.
