Can somebody respond to my question of the benefits of square jetting/blocking the PV in terms of throttle response/consistency for a 3000 rpm/stutter 2-step launch on a 5000 stall converter. Am I likely to see any real difference (60' et improvement) since I'm essentially shooting off the rear pump shot anyway? I mean it seems logical to me (take the potential PV "flutter" out of the equation and truly equalize the A/F ratio from F/R) but want to get my head around the real reasoning or something I'm not considering. I know it's easy enough to try but before I do I want to hear other opinions....thanks!

The 1000HP 4150 carb was originally on a 508" street driven Big block where the PV was beneficial for cruising.
