I mistakenly gave my input to this Carbs subject under the Performance Pushrod subject a day ago..
My input was that I had similar experience dealing with a Holley 390 carb on a 302 GMC. It bogged down just after takeoff. I went thru 10 power valves but could not fix the bog. The Holley transition from low to medium speed was the problem.
I have run 3 32/36 Webbers on my GMC 302 for 24 years with no bogging problems and good performance. The low to medium speed transition is smooth.
