Are they using a Q-jet with its tiny fuel bowl or Hollys that have 2 large bowls?
I'm under the assumption that a Q-jet's little bowl has a hard time keeping up once your well over stock HP levels, hence the need for a steady & efficient fuel supply. Maybe my thinking on this has nothing to do with how starvation happens?
I'm keeping an eye on this thread, l have what may be a thirsty 455HO with a quadrajet in the works and I want to get it right.
