GS - I just got off the phone with Pierce Manifolds in CA and the problem is simply too much airflow over the stacks. If you look at the 289 Cobra's with Webers they run a filter/reducer in the hood scoop which solves this problem. Ferrari's use a little aluminum wall which I'm having fabricating later today. I have them tuned and they idle at 1,000 and spin the tires through 5K rpm's.
