I have a lightweight Fibreglas Trends race hood with a SS/AH stock type scoop molded on, it was trying to flyoff at 124 MPH It starts bulging upwardss around 121 or so MPH and gets worst the faster I go I really worrry now that it runs 134+ MPH in the 1/4 I don't have the four bolts across the front like the stockers came with, I used two do to running a six pak on the motor My message is a molded on hood scoop can cause issues also
