I will agree 500 HP is about the limit for a stock intake. My first ported E head 455 259/264 SR I kept the HO intake until I found an extra Shaker base to "massage" for a Holley/Demon. After I found one swapping a Demon with an adapter for the worked Qjet at the track picked up 0.3 seconds. Swapped a Torker II on idled smoother and with jetting the car ran 10.90@123 in good air, 6.9 1/8 at 99 weighing 3750.
