Cam change effect on 60' times ?

I played with intakes, but I can only say what it did for me. My intake has the divider cut down, made a divider. The car needs the plenum volume up top more than any gained torque down low. I made an intake with HUGE open plenum. Knew it was not going to work and it didn’t. Slowed down 2/10’s, but have not given up on it yet. No time to play with it right now.
