Anybody Actually Goin' Fast With a Holley 3 BBL?

I'll tell 'ya.......I agree that Vacuum Secondaries Carbs can be made to run hard, especially advantageous on a traction limited car. Up until a just a few years, Holley even had a 950 HP Model that was available with Vacuum Secondaries. We had one on a buddy's 454 Nova that ran 10.50-60's like clockwork on a 28-10.5 Mickey. It was a great carb and sometimes I wish I had socked that one away for a future application. Unfortunately, they were discontinued because everyone wanted the double pumper version.
